$- S_{3} + - O_{2} - S O_{3}$

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 $1 \cdot - 1 = - 1$

$- S_{3} - O_{2} - S O_{3}$

Step 2

Move $S$ .

$- S_{3} - O_{2} - 1 O_{3} S$

Step 3

Move $- S_{3}$ .

$- O_{2} - 1 O_{3} S - S_{3}$

Step 4

Reorder $- O_{2}$ and $- 1 O_{3} S$ .

$- 1 O_{3} S - O_{2} - S_{3}$
