-3 + 12 is the same as saying 12 + -3 which is the same as 12 - 3
12 - 3 = 9
Look at a number line. Start at -3. Then move to the right 12 spaces. You land on number 9. Negative three means that on a number line it is three spaces to the left of 0. All negative numbers are to the left of zero on a number line and are less than zero. Hope that helps!

+9. You can either switch it around as 12 -3, or you can add 12 to -3. Either way, you get +9.

it is 9. 12-3= 9. subtract the bigger number from the smaller one and then put the symbol of the bigger number. i
eg:
-6 + 5
the answer is -1. because 6-5=1 and 6 is the bigger numer and has negative symbol on it.

Look at it on a number line to understand.
If you start at -3 and go up 12 steps, what number will you be on?
