what is twelve times a number?

Question

write the expression using mathematical symbols 

Answer 1

In addition to Justin's answer, we can say

 

 

12 * x             and               12(x)

 

Using the asterisks and parenthesis are also symbols to represent multiplication in algebra.

 

 

We never use the cross symbol (×) from elementary math, for it will cause confusion with the variable x.

Answer 2

"Twelve times a number" means that you are taking a number x and multiplying it by 12, so your mathematical expression would be 12x.
