Question

Drag each tile to the correct box.

Using the order of operations, what are the steps for solving this expression?

40=8+32 +(15–7)x2

Arrange the steps in the order in which they are performed.

3 “squared”

15-7

14 +16

40:8

8x2

5+9

Answer 1

1. 15 - 7 (Parentheses)
2. 3² (Exponents)
3. 8 × 2 (Multiplication)
4. 40 ÷ 8 (Division)
5. 5 + 9 (Addition starting from the leftmost)
6. 14 + 16 (Addition after the first addition operation)

Concept:

When encountering questions that ask for simplifying expressions through operation, following the PEMDAS method would be easier:

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

Therefore, the whole process of simplifying the given expression should follow the PEMDAS method. For extra, whenever there are two occurences of the same operation, then prioritize the leftmost and go right.

Hope this helps!! :)
