Good Lifestyle

Unless your career took you in mathematics or engineering, chances that you do not regularly find trigonometric or complex calculation. But you probably use the basic mathematical concepts you had to master at the grade school almost every day, that you determine to determine how to install the furniture in your living room or a way to reduce the time of your trip.

Nevertheless, while you use many concepts of the sixth year, it has probably been a bit since you've been looking at what you really know - and you might be surprised by your dead mathematical corners. To test what you know - and, more importantly, what you do not have, here are 30 questions that any sixth grader right would be capable of ACE. (Note: They increase the level of difficulty!) And to get an idea of ​​more tests, you can or not able to be able to check howOur journalist took the president's cognitive test (and here they scored).

The "-" here shows that these are negative numbers, which means they are less than zero.

Negative 2 is larger than negative five. To help you think about negative numbers, think of a board game where "bigger" means "closer to the finish line". Imagine that a red piece and a blue room start at the same place (zero). The red piece must retreat 2 spaces (-2). The blue piece must retreat 5 spaces (-5). Which one is closest to the finish line? Red!

I bet you did not know that you should learn a new vocabulary in mathematics class! And to brown your non-mathematical lexicon, start memorizing these47 Cool foreign words that will make you sound sophisticated.

The fractions are numbers separated vertically by A - or A /. Decimal numbers have a period of a period that, in mathematics is called a decimal point. Whole numbers are numbers without fractions or decimal points, even if they are negative numbers. And for more ways to point your mind,Try these cerebrkets to find out if you are smarter than an astronaut.

Tip: If you do not remember how to convert percentages in decimal places, simply delete the percent sign and move the decimal point two locations on the left.

0.85 x 21 = 17.85 or, to put it in a sentence, 85% (x) 21 is (equal) 17.85.

Be comfortable with decimals - you need to know how to add, subtract, multiply and divide them.

The addition and subtraction of decimal numbers is not as difficult as it seems. Do not forget to set up decimal points and put zeros in all right columns that do not have numbers if necessary (ex: 8.5630 + 4.8292). And for other twisters brains, see howOur correspondent took the cognitive examination of the NFL and here were what they learned.

This is a simple algebraic expression. Algebra is simply the use of mathematics symbols.

Any letter can be used as variable (or unknown number). In this case, it's tiny "U". So, simply connect the number for the variable and you get 47 - 23 = 24. Next,Increase your brain with this science-proven trick!

This is called an algebraicsquareBecause the number on both sides of the equal sign must be identical.

Since we know thatTo Stands for an unknown number and the numbers on both sides of the equal sign must match, we ask: "What number can be subtracted from 9 to equal 8?"

These mathematical statements are called inequalities. Unlike equations, the numbers on each side of do not necessarily have to be equal.

If you read it aloud, you would say that "6 is less than 7," so 6", it would say that "7 is greater than 6." So, is the "superior than" symbol.

Independent and dependent variables are also used in scientific experiments.

The independent variable is something you have control in this case you can decide on the number of household tasks to do. The dependent variable is something that depends on the independent variable - in this case, how much money you bring to you depend on the number of tasks you make. This number will change as evolution of the independent variable. And for more ways to sharpen, start playing theAdvanced video games that will make you smarter.

The study of triangles is called trigonometry. You will not learn everything you need to know about triangles in 6th year, but you will make a good start!

The area of ​​a triangle is equal to its base multiplied by its height (5 x 4 = 20) divided into two (20 ÷ 2 = 10). You will see this formula written asA = ½ bh.

The graphics are aExcellent way to visualize and compare numbers. Bar graphs (or graphics) are one of the most common types.

We first examine the Y axis (vertical) to find what we have said to look for: pie charts. We then travel along the X (horizontal) axis to see where the bar ends: 2. It means that there were two occurrences of people saying "my favorite graph is a pie chart."

The average of a group of numbers is sometimes called "average".

The average is calculated by adding the numbers in a set set (5 + 3 + 6 + 2 = 16) and dividing this response by the number of elements in the assembly (16 ÷ 4 = 4).

To divide the fractions, you multiply reciprocity. Do not worry, it's not as complicated as it sounds!

Multiply the numerator or the top number, the first fraction (4) by the denominator or the lower number, of the second fraction (2) to obtain the numerator of the response (4 x 2 = 8). Then, multiply the denominator of the first fraction (5) by the numerator of the second fraction (1) to obtain the denominator of the response (5 x 1 = 5). Then simplify 8/5 in 1⅗.

The absolute values ​​are usually written between ||, you can also write this question as | -8 | =?

The absolute value of any number, positive or negative, is always positive. You can think about it as the distance from zero on a digital line. The 8 and -8 both have the same absolute value of 8, since they are all 8 whole digits of zero. And for more ways to hinder your mind, start eating theThe top 50 foods for your brain.

This process is called combination of terms.

As long as the numbers are combined with the same variable (in this case,a), You can add, subtract, multiply or divide them as if the variable is not there. You can even think of the variable as a physical object. If you have 4 apples and give you 2 extra apples, how many apples do you have now?

A parallelogram is a four-sided shape composed of two pairs of parallel lines.

You can find the area of ​​a parallelogram by multiplying its base by its height. This formula can also be written asAFrancizeBHSo 5 x 4 = 20.

In mathematics, a Superscript number is an exhibitor, which means a repeated multiplication will be necessary to find the answer.

An exhibitor tells you how many times multiply the basic number to get the total number. It is commonly used to simplify long numbers, because 10⁹, for example, is much easier to work with 1,000,000,000 (nine zeros).

You will need to know how to find the factors of any given number, then compare them.

The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18 and 36. The factors of 12 are 1, 2, 3, 4, 6 and 12. The greatest number they have in common are 12

A chart of the box is a graphic is a way to show the propagation and form of the data. "Data" is just a word of fantasy for a set of numbers, often numbers corresponding to the results of a survey or experience.

The box in a plot of the box shows the middle 50% of a range of numbers. Inside this box is a line identifying the median, or the value that would be right in the middle if you have lightened all the lowest numbers at the highest. For example, the middle of 50% of the range 2, 3, 6 and 8 would be 3 to 6 years and the median would be 4.5. In the box graph above, the line of the median appears between 8 and 10 to about 8.5.

Multiply and divide the decimal numbers is not so difficult if you remove the decimal room ... but do not forget to put it back!

At first, pretend that 1.92 is an integer: 192 with two decimals. Then divide 192 by 3 to obtain 64. Now, now put the two decimals to get a final answer of 0.64.

Know your dozens, hundreds and thousands, but do not put them confused with the tenths, hundredths and thousandths!

The 2 is in the hundreds column and the next number on the right (the TENS column) is a 9, which means you have to round.

This type of graph is called a histogram, but you can use the same conditions to describe the plots, bar graphs and plots of the box.

Since the shape that these data constitute (about) the same shape on either side of a central axis (in this case, the zero point of the X axis), it is symmetrical. As it reaches its highest peak on the Y axis in the middle, we say it is bell-shaped.

You will have some centimeters remaining.

There are 12 inches on foot, so 272 divided by 12 is 22 with a rest of 8.

The multiples and factors are closely linked.

The largest number of multiple multiple (sometimes abbreviated) is the lowest number that is divisible by both (or more) integers in consideration. Thus, 208 is the lowest number that can be divided evenly by both 16 (208 × 16 = 13) and 26 (208 ÷ 26 = 8).

The surface is the sum of the areas of all forms which constitute the outside of a three-dimensional figure.

Rectangular shapes, such as cardboard boxes, have 6 exterior faces: up and down, front and rear, left and right. The formula for calculating this surface of the surface is (length x width) x 2 + (length x height) x 2 + (width x width) x 2. Here it means (4 x 3) x 2 = 24, (4) x 7) x 2 = 56, and (7 x 3) x 2 = 42. Add the set: 24 + 56 + 42 = 122 In².

To add or subtract fractions, they must have the same denominator.

First, you must find the common denominator lowest or the lowest number that is divisible by both numbers less on fractions. For 12 and 5, that number is 60. Then you must convert each denominator. Since you have to multiply 12 to 5 to 60, 7 x 5 Multiply to get 35/60. Since you have to multiply 5 of 12 for 60, 2 Multiply by 12 to also get 24/60. Now you can add: 35/60 + 24/60 = 59/60. You can not simplify 59/60 away, then this is your answer!

It is important to know how to navigate the points on a coordinate plane. You may be asked to find the area of ​​shapes on a grid coordinate.

The first pair number is the location on the X axis (horizontal); The second number is the location on the Y-axis (vertical). Your screen should look like the above.

The volume of a shape is the amount of things that can fit inside. The two-dimensional shapes such as squares have no volume, but the three-dimensional shapes such as cubes.

You find the volume of any rectangular box by multiplyinglength throughwidth throughthe size. Because all the edges of a cube are the same length, 10 x 10 x 10 = 1000.

PI is a constant number, not a delicious dessert! Learn to use IP (π) for calculating the area or circumference of a circle.

Find the circumference of a circle by multiplying PI (π = 3.14) in diameter (7.7 ft).

This problem requires that you convert into numbers mixed ages and to subtract.

To subtract numbers mixed, convert them to incorrect fractions and follow the same procedure to add and subtract fractions. For three months, ¼ of a quarter of one year and six months half of the year, the problem runs 9 ¼ - 2 ½. Convert two districts, therefore 37/4 = 9 ¼ to 2 ½ = 10/4. 37/4 - 10/4 = 27/4. Simplify 27/4 6¾. Three quarters of a year have nine months. So the answer is 6 years and 9 months.

Like athe bite rotates a human in a zombie, You transform these numbers into fractions!

The ratio tells us that for 2 zombies, there are 3 humans, which gives us a group of 5 (2 + 3) persons. Divide the total (85) in groups of 5, obtaining 17 groups. Multiply by those numbers ratio of origin, there are (17 x 2) 34 zombies and (17 × 3) 51 humans.
