That is why it is called a mixed fraction or mixed number. 3 Types of Fractions There are 3 types of … Continue reading "Mixed Fractions"
Read MoreHow To Find if Triangles are Congruent
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 … Continue reading "How To Find if Triangles are Congruent"

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 … Continue reading "Equal, Greater, or Less Than"
Read MoreImplicit Differentiation
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 … Continue reading "Implicit Differentiation"

A linear equation is an equation for a straight line. Different Forms There are many ways of writing linear equations. They usually have constants (like “3” or “c”) and must have simple variables (like “x” or “y”). The variables (like “x” or “y”) in Linear Equations do NOT have: Exponents (like the 2 in x2) Square … Continue reading "Linear Equations"
