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.

Let the number be a a + 8
7 + 8 * n
8-x
The algebraic expression for "8 more than half a number" can be represented as ( \frac{x}{2} + 8 ), where ( x ) represents the unknown number. This expression first calculates half of the number by dividing it by 2, then adds 8 to the result.

N/8
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
s= -8 + n, or s=n - 8, where s is the sum and n is the number
