$2 + - 5 \leq 5 + 2$

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 $1 \cdot - 1 = - 1$

$2 - 5 \leq 5 + 2$

Step 2

The left side $- 3$ is less than the right side $7$ , which means that the given statement is always true.
