Numerical expressions have numbers and signs.
Plus signs, minus signs, divide by and times.
5 plus 2 or 3 times 9
with no equal sign.
You can write an expression to show a situation,
then do the order of operation.

[Verse 2]
An algebraic expression uses a letter to stand for your variable.
A variable is a symbol used to represent a number in an expression.
You have 5 times C or 3 minus X,
or maybe D plus 2.
Replace the letter with the number you choose,
then do order of operation.
