# How do you solve 4 times 7 plus a number is 28?

Nov 15, 2016

The number is $0$

#### Explanation:

If we let the number be represented by $n$
there are two interpretations of this question:
$\textcolor{w h i t e}{\text{XXX}} 4 \times \left(7 + n\right) = 28$
and
$\textcolor{w h i t e}{\text{XXX}} \left(4 \times 7\right) + n = 28$

Fortunately (or coincidentally) both simplify to $n = 0$
