Explain how to translate the phrase into an algebraic expression.four times the difference of eight and a number?
Sample Response: Replace key words with variables, numbers, and operations. The words “four times” means multiplication by 4. The words “the difference of” means subtraction inside of parentheses. The subtraction inside the parentheses will be 8 – n because that is the order they appear in the phrase. The expression is 4(8 – n).

Write one numerical expression and one algebraic expression then explain the difference between a numerical and algebraic expression is?
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
Write one numerical expression and one algebraic expressionThen explain what the difference between a numerical and algebraic expression is?
Numerical expression: 59-34*6 Algebraic expression: 5x-3x+2 A numerical expression is limited to only numbers and can always be simplified to one number. An algebraic expressuion uses terms, more specifically a variable like x, and a constant like 2.
