Which two signs should be interchanged to make the following equation correct?…

Step-by-Step Verification
Let's test the options by swapping the operators:

Option 1: Swap ÷ and ×
Equation becomes: 437 × 23 + 34 – 26 ÷ 170 = 733

437 × 23 = 10051

26 ÷ 170 ≈ 0.15

10051 + 34 - 0.15 = 10084.85

Result: Incorrect.

Option 2: Swap × and +
Equation becomes: 437 ÷ 23 × 34 – 26 + 170 = 733

437 ÷ 23 = 19

19 × 34 = 646

646 - 26 + 170 = 790

Result: Incorrect.

Option 3: Swap × and –
Equation becomes: 437 ÷ 23 + 34 × 26 – 170 = 733

437 ÷ 23 = 19

34 × 26 = 884

19 + 884 - 170 = 733

Result: Correct.

Option 4: Swap ÷ and +
Equation becomes: 437 + 23 ÷ 34 – 26 × 170 = 733

23 ÷ 34 ≈ 0.67

26 × 170 = 4420

437 + 0.67 - 4420 = -3982.33

Result: Incorrect.
