Four times a number

Question

Algebraic expression 

Answer 1

I find it helpful to replace the words with the mathematical operation (+, -, x, /).

 

For this problem:

four --> 4

times --> x (multiplication)

a number --> any variable (sometimes the problem says to use a specific variable, but since it does not say what to use, I'm going to use "a". You can use whatever variable you want, such as "x", "b", "c", etc.)

 

Thus, the algebraic expression is 4a.
