Work Step by Step
According to the last step of order of operations, we must evaluate addition and subtraction from left to right.
First, we only consider $4-(-4)$. Change the minus sign to a plus sign and insert the opposite of the second number in place of the second number.
$4-(-4)=4+(4)=4+4=8$
Next, we can subtract -3 from 8.
$8-3=5$
