Answer

To make this calculation correct, we can insert brackets as follows:

5×(3−1)=105 \times (3 - 1) = 10

This correctly simplifies to:

5×2=105 \times 2 = 10

Thus, the expression evaluates to 10.

Step 2

3 + 6 − 2 ÷ 2 = 3.5

Answer

To correct this calculation, we can insert brackets like this:

(3+6−2)÷2=3.5(3 + 6 - 2) \div 2 = 3.5

Breaking this down:

  1. Calculate the expression inside the brackets: 3+6−2=73 + 6 - 2 = 7
  2. Now divide by 2: 7÷2=3.57 \div 2 = 3.5

Thus, this expression evaluates correctly to 3.5.
