$- 5 + (- 3 - - 3) (- 3 + - 5)$

Step 1

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

$- 5 + (- 3 + 3) (- 3 + - 5)$

Step 2

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 $1 \cdot - 1 = - 1$

$- 5 + (- 3 + 3) (- 3 - 5)$
