Apr 1, 2016

We use order of operations to determine the answer of 52.

#### Explanation:

We use the order of operations sometimes referred to as BEDMAS or PEDMAS for Brackets, Exponents, Division, Multiplication, Addition and Subtraction. Starting with the expression we work through each item in order:

$8 \cdot 7 - 4$

Brackets: none.
Division: none.
Multiplication: yes!

$\textcolor{red}{8 \cdot 7} - 4 = \textcolor{red}{56} - 4$

$\textcolor{b l u e}{56 - 4} = \textcolor{b l u e}{52}$
