the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.
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.
The algebraic expression for 11 minus the product of 5 and a number can be written as 11 - 5x, where 'x' represents the unknown number.
(10)(2x)
n*35 or 35n
the product of a number and ninety-six

If n is the number 5n is 5 times the number.
x-5
the product of 23 and a number
No, but by convention, they usually are. For example, they can be algebraic expressions.

An Algebraic expression is any expression (equation) that contains a letter where a number should be.
