Help me solve this problem, I am lost here.
These are integers,
15-12-8=
also 4-(-7)-9=
and -11-(-5)-(-6)=
15-12=3
3-8=-5
4-(-7)=4+7=11
11-9=2
-11-(-5)=-11+5=-6
-6-(-6)=-6+6=0

Sure, I can help you solve these problems step by step!
1. To solve 15 - 12 - 8, start by subtracting 12 from 15:
15 - 12 = 3
2. Then subtract 8 from the result:
3 - 8 = -5
So, 15 - 12 - 8 = -5.
Now let's move on to the next problem:
1. To solve 4 - (-7) - 9, first, simplify the expression inside the parentheses:
(-7) is the same as -1 * 7, so when you remove the parentheses, it becomes 4 + 7 - 9.
2. Now, add 4 and 7:
4 + 7 = 11
3. Finally, subtract 9 from the result:
11 - 9 = 2
So, 4 - (-7) - 9 = 2.
Now for the last problem:
1. To solve -11 - (-5) - (-6), remember that subtracting a negative number is the same as adding. So, when you remove the parentheses, it becomes -11 + 5 + 6.
2. Next, add -11 and 5:
-11 + 5 = -6
3. Finally, add 6 to the result:
-6 + 6 = 0
So, -11 - (-5) - (-6) = 0.
By following these step-by-step instructions, you can solve these integer subtraction problems.
