The numerical expression (36÷4⋅3)−8+10 is simplified as follows. In which step, if any, did the first error occur?
Step 1: (9⋅3)−8+10
Step 2: 27−8+10
Step 3: 27−18=9
A)Step 1
B)Step 2
C)Step 3
D)No error occurred.
The first error occurred in Step 1: (9⋅3)−8+10.
The expression should be simplified in the correct order of operations, which is Parentheses, Exponents, Multiplication/Division (from left to right), and Addition/Subtraction (from left to right).
In this case, the division should be performed first, so the correct expression in Step 1 should be: (36÷4)⋅3−8+10.
