Step-by-step explanation: Pemdas
According to Khan Academy, "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)."
849-1.5=847.5
6.8-4.8=2
847.5 divided by 2 =423.75
