Step-by-step explanation:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
7×3 -4(225÷32)×2
7×3 -4(7.03)×2
21 - 8 (7.03)
21 - 56.25
= - 35.25
