# If the expression 3-4^2+6/2 is evaluated, what would be done last?

Nov 16, 2016

#### Explanation:

Order of evaluation:

Parentheses (none in this case)
Exponentiation: ${4}^{2}$
Division and Multiplication: $\frac{6}{2}$ (no multiplication)
Addition and Subtraction: there is a minus and a plus
$\textcolor{w h i t e}{\text{XXX}}$-when there are multiple operations at the same level
$\textcolor{w h i t e}{\text{XXX}}$they are performed from Left to Right.
$\textcolor{w h i t e}{\text{XXX}}$Since the minus appears to the left of the plus
$\textcolor{w h i t e}{\text{XXX}}$the minus occurs first (and the plus last).
