Step 1 :

  • Step 1 [ 8 ÷ 2 + (3+1) ] is where the first mistake occurred.
  • To evaluate 8 ÷ 2 + (3 x 3 - 2) , we will follow the rule of BODMAS .

Step 1

  • 8 ÷ 2 + (9 - 2)

Step 2

  • 8 ÷ 2 + 7

Step 3

  • 4 + 7

Step 4

  • 11

Hence, the solution would be 11 instead of 7 and thus,the entire solution given was wrong.

Answer:

Mistake appears in step 1

Explanation:

The first mistake in the evaluation of the expression:

8 ÷ 2 + (3 × 3 - 2) appears in Step 1.

According to the order of operations, multiplication and division should be done before addition and subtraction.

So, the correct evaluation should be:

Step 1: 8 ÷ 2 + (9 - 2)

Step 2: 8 ÷ 2 + 7

Step 3: 4 + 7

Step 4: 11

The expression evaluates to 11, not 7.
