Subtraction of integers practice worksheet with 30 problems.

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

---

🔷 Rules for Subtracting Integers:

1. Subtracting a positive number:
$ a - b = a + (-b) $

2. Subtracting a negative number:
$ a - (-b) = a + b $
*(Subtracting a negative is the same as adding a positive)*

We'll go through each problem and solve it.
