Subtracting Mixed Integers from -15 to 15 (75 Questions) (A) - Free Printable

Let's solve the "Subtracting Integers (A)" worksheet step by step. The goal is to calculate each difference, applying the rules for subtracting integers.

---

🔷 Rule Reminder:

To subtract integers:
> $ a - b = a + (-b) $

This means subtracting a number is the same as adding its opposite.

Also remember:
- Subtracting a negative is like adding a positive.
> $ a - (-b) = a + b $
- Subtracting a positive is like adding a negative.
> $ a - b = a + (-b) $

Now let’s go through each problem and solve it.
