Math Substitute Given Values to Evaluate Expression

Match the term to its definition.

Variable

• A product formed from repeated multiplication by the same number or expression. Consists of base and an exponent.

• A letter that is used to represent one or more number.

• Substitute values for the variables and then simplify the resulting numerical expressions.

• A number that represents how many times a base is used as a factor in a repeated multiplication.

what happens when you take a value and put it in place of a variable.

• substitution

• coefficient

• prime factorization

• order of operations

when you evaluate expressions and solve equations. evaluate means to substitute any values given for the variable and then work through the order of operations is ______.

• evaluate vs. solve

• prime factorization

• power

• base

When you __________ an expression, you substitute values given for variables and perform the order of operations.

An example would be: 1x + 3 when x=4 gives the value of 7.

• organize

• solve

• simplify

• evaluate

The number or numbers that when you substitute them into an equation makes the equation true.

An example would be 3x - 2 = 10 , the ___________ is 4.

• equation

• expression

• area

• solution

Which of the following is an expression?

• 5x + 2 - 8 = 25

• 14 = 5y

• 2h + 8

• 9 - r = 17

What does "evaluate" mean in math?

• write a number using exponents

• a mathematical phrase involving at least one variable and sometimes numbers and operation symbols

• breaking down a composite number until all of the factors are prime

• substitute any values given for the variable and work through the Order of Operations.
