the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.

use a calculator

x+x use inverse operations

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.

2-9h+6-5n use h=3 and n=2

Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)

I think it is important because you need to know it when you get older.

They can be used to simplify expressions so that the solutions can be found more easily.
