Answer
20
$14-5\times3+3^2$
Work Step by Step
Use the order of operations to evaluate.
$14+5\times3-3^2\longrightarrow$ resolve exponent
$=14+5\times3-9\longrightarrow$ multiply
$=14+15-9\longrightarrow$ add and subtract working left to right
$=29-9\longrightarrow$ subtract
$=20$
Changing the addition to subtraction and the subtraction to addition will give a result of 8.
$14-5\times3+3^2\longrightarrow$ resolve exponent
$=14-5\times3+9\longrightarrow$ multiply
$=14-15+9\longrightarrow$ add and subtract working left to right
$=-1+9\longrightarrow$ subtract
$=8$
