$n_{2} + o_{2} - - - - 2$ no

Step 1

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

$n_{2} + o_{2} + 2$

Step 2

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

$n_{2} + o_{2} + 2$
