# How do you simplify (2 + 3) + 42 xx (5 − 3)?

Nov 8, 2016

$89$

#### Explanation:

Rather than blindly following PEDMAS, BODMSA, etc in whatever you know it, count the number of term first. Each term will simplify to a single answer and these are added or subtracted in the last step.

In each term the order is:

• brackets first,
• powers and roots
• multiply and divide

color(blue)((2 + 3)) color(magenta)(+ 42 xx (5 − 3))" "larr has 2 terms

$= \textcolor{b l u e}{5} \textcolor{m a \ge n t a}{+ 42 \times 2}$

$= \textcolor{b l u e}{5} \textcolor{m a \ge n t a}{+ 84}$

$= 89$
