Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
Numerical Expression
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
Algebraic Expression
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
