12 - (-3) =
what does it equal

-15

Step-by-step explanation:

12 + 3 = 15 now add the - sign since the signs are the same

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

it would rotate about 180 degrees.
