A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Chapter 4.5, Problem 3ES

For each step, write the letter that gives an explanation of what was done on that step.

a. Combining like terms

b. Multiplying monomials

c. Using the commutative law for multiplication

d. Using the distributive law

( 2 x + 3 ) ( 5 x − 4 ) = ( 2 x + 3 ) ( 5 x ) − ( 2 x + 3 ) ( 4 ) = ( 5 x ) ( 2 x + 3 ) − 4 ( 2 x + 3 ) = ( 5 x ) ( 2 x ) + ( 5 x ) ( 3 ) − 4 ( 2 x ) − 4 ( 3 ) = 10 x 2 + 15 x − 8 x − 12 = 10 x 2 + 7 x − 12
