Evaluating Math Expressions using the GEMDAS rule

Показать описание
GEMDAS
(Abbreviation) A math brain tip or trick used to remember the order (PEMDAS is not as accurate) of how to do numerical expressions.
1) G Grouping () l l {} or square root
2) E Exponent
3) MD or DM Multiplication & Division~left to right
4) AS or SA Addition & Subtraction~left to right
Usage: -5^2 + 8 / 2 x 4
-25 +8 / 2 x 4
-25 +4 x 4
-25 + 16
-9
