# How do you write the algebraic expression: a number q tripled?

Sep 16, 2016

$3 q$

#### Explanation:

To "triple" something means to multiply it by 3, in the same way that "double" means multiply by 2,

"A number" can simply be called $x$

"A number, q, tripled" can be written as $3 q$

This should not be confused with "a number cubed" which is written as ${q}^{3}$
