$- 2 + - 4 = - 6$

Step 1

Replace all occurrences of $+$ $-$ with a single $-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because $1 \cdot - 1 = - 1$

$- 2 - 4 = - 6$

Step 2

The left side $- 6$ is equal to the right side $- 6$ , which means that the given statement is always true.
