Answer: 57
Step-by-step explanation:
1. Calculate what's in the parentheses first
(4 * 15) = 60
(60) - 3 = ?
2. Exponents (Powers, Roots) before you Multiply, Divide, Add or Subtract
Not applicable for this problem.
3. Multiply or Divide before you Add or Subtract
Not applicable for this problem.
4. For anything else left, just go from left to right
60 - 3 = 57
If you want to remember the shortcut; PEMDAS
P - Parentheses first
E - Exponents (Powers and Square Roots, etc.)
MD - Multiplication and Division (left-to-right)
AS - Addition and Subtraction (left-to-right)
Remember that:
Divide and Multiply rank equally (and go left to right).
Add and Subtract rank equally (and go left to right)
