How to Square A Number To square a number: Multiply the number by itself. “Squared” is often written as a little 2 like this: 42 = 16 This says “4 Squared equals 16“ (the little 2 says the number appears twice in multiplying) Perfect Squares The Perfect Squares (also called “Square Numbers“) are the squares of
In geometry, 2 figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. Definitions of Congruent Angles Angles are congruent if they have the same angle measure in degrees. They can be at any orientation on
Complementary comes from Latin completum meaning “completed“, because the right angle is thought of as being a complete angle. Definition of Complementary Angles Complementary angles are 2 angles whose measures add up to 90o. For example 2 puzzle pieces that form one 90o angle when they are put together. Complementary angles are always in a pair. One
Mixed Fraction is also known as Mixed Number A Mixed Fraction is a whole number and a proper fraction combined. Each example is made up of a whole number and a proper fraction together. That is why it is called a mixed fraction or mixed number. 3 Types of Fractions There are 3 types of
Triangles are congruent when all corresponding sides & interior angles are congruent. The triangles will have the same size & shape, but 1 may be a mirror image of the other. 2 triangles are congruent if they have: exactly the same three sides and exactly the same three angles. We don’t have to know all 3

A fractional exponent is an alternate notation for expressing powers and roots together. Fractional Exponents are also known as Radicals or Rational Exponents. Whole Number Exponents First, look at whole number exponents: The exponent of a number says how many times to use the number in a multiplication. Fractional Exponents Remember that when aa is a
As well as the familiar equals sign (=) it is also very useful to show if something is not equal to (≠) greater than (>) or less than (<) Equality and Inequality Definition In mathematics, equality is a relationship between 2 quantities or more (generally 2 mathematical expressions) asserting that the expressions represent the same
What are rational numbers Numbers are core of mathematics. Almost all of mathematics parts consist of numbers. There are some types of numbers. One of them is rational numbers. Rational numbers were invented by Greek mathematician, Phytagoras. Rational numbers consist of natural numbers and integers. Rational numbers symbolized as boldface Q (Q). It is type
Some equations in x and y in mathematics do not explicitly define y as a function x and cannot be easily manipulated to solve for y in terms of x, even though such a function may exist. If it happen, it is implied that there exists a function y = f( x) such that the given
