Math Answers: Addition

Addition is the process of combining two or more numbers. The plus sign (+) is the mathmatical notation used to indicate addition. A common format for addition equations is: 3 + 3 = 6. Find out more about addition and get the math answers you're looking for with these resources.

Math Answers: Algebra

Algebra is an area of mathematics that solves equations using variables, often represented by symbols in equations. Because algebra uses variables to stand for numbers, it helped create mathmetical laws such as the transitive property: a + b = b + a.

Algebra has been used to invent some fundamental mathmetical equations that yield useful math answers. These include the Pythagorean Theorem and the Quadratic Formula. Find out more about algebra and get the math answers you're looking for with these math resources:

Math Answers: Division

Division can be thought of as reverse multiplication: instead of adding a number multiple times, it's essentially subtracting a number several times. There are several ways to write a division problem. One is using this symbol: ÷. An equation would be written as follows: 8 ÷ 4 = 2, and would read "eight divided by four equals two." Another way to write division problems is as fractions. For example: 8/4 = 2. In this situation, the forward slash ( / ) is used to mean the same as ÷.

Math Answers: Fractions and Decimals

Fractions and decimals deal with non-integers. These numbers are between integers. For example, the fraction 3/2 is the same as the decimal 1.5, which is a number between one and two.

While decimals are useful for expressing simple, rational numbers, fractions are often used to express irrational numbers. Irrational numbers are difficult to write as decimals because they are non-terminating -- they have an infinite number of digits.

A useful point to remember about fractions is that the top of the fraction is called the numerator and the bottom is called the denominator. When simplifying fractions, one must find a number that divides evenly into both parts of the fraction.

Math Answers: Geometry

Geometry is a branch of mathematics that deals with angles, points, planes, lines and shapes, and their relationships to one another. Geometry often uses "proofs" to establish theorems and laws. These are step by step instructions that clearly show how each stage of a problem is solved. Find out more about geometry and proofs and get the math answers you're looking for with these resources.

Math Answers: Probability & Statistics

Probability and statistics are the study of how likely a particular outcome is based on analysis of historical data. Math defines probability between zero and one. If something is completely impossible, its probability is zero. If something always happens, its probability is one. If something happens three quarters of the time, that event has a probability of .75. To find out more about statistics and probability and get related math answers, try these useful resources.

Math Answers: Trigonometry

Trigonometry is the study of the properties and relationships of the parts of a triangle. The most basic elements of trig are sine, cosine and tangent. A helpful way to remember the definitions is the phrase "soh-cah-toa." This is an easy way to remember that sine is the opposite side divided by the hypotenuse, the cosine is the adjacent side divided by the hypotenuse, and the tangent is the opposite side divided by the adjacent side.
