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.

None of the expressions on that list is a numerical one.

what mathematicians agreed on an so that numercial expressions would have only one value?

A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols. The following are some examples of numerical expressions. For example, the numerical expression 4 + 20 - 7 in the example above simplifies to the number 17.

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)

There is only one extra rule to algebraic expressions over normal numerical expressions: when two letters are next to each other it means multiply them together: ab means a times b The multiplication symbol is omitted as it looks too much like the letter 'x' can could be confused as such.
