How does -1.125 + 1.2 = 0.075 instead of 0.925?

.0075 (hope this help; let me know if not)

Step-by-step explanation:

The operation is + and the signs of the numbers are opposite so we have to subtract. The bigger number has positive sign in front if so we do 1.2-1.125=1.200-1.125

I'm going to line up

1.200

-1.125

If you have 200 and you take about 125... 75 should beleft

so

1.200

-1.125

0.075

your answer would be that the sematry would be vertical semmetry
