Question

how do you solve this problem 12-(-3) step by step

Answer 1

The - sign in front of the () is the same as -1.  So, you will take -1 and multiply it by -3. - 3 × -1 = 3.  When you multiply two negative numbers together the resulting number will be positive.  Now, you have 12 + 3 = 15.  The solution is 15.
