$2 - - 2 = - 4$

Step 1

Replace all occurrences of $-$ $-$ with a single $+$ . Two consecutive minus signs have the same mathematical meaning as a single plus sign because $- 1 \cdot - 1 = 1$

$2 + 2 = - 4$

Step 2

The left side $4$ does not equal to the right side $- 4$ , which means that the given statement is false.
