Question

If the signs ‘+’ and ‘-’ are interchanged in each of the given equations, then which one equation would be correct?

• A. \(8 \times 2 - 3 + 2 = 3 \times 2\)
• B. \(8 - 2 + 6 \times 8 = 6 - 6\)
• C. \(6 + 4 - 4 = 5 + 4\)
• D. \(4 \times 6 - 3 + 2 = 4 \times 2\)

Hint:

In such problems, always start by applying the changes systematically to verify if the equation holds true.

Answer 1

The Correct Option is D

By switching the signs of ‘+’ and ‘-’, we check each equation, and the only one that holds true is option (4).
