Math worksheet for subtracting integers, featuring 30 problems to calculate differences between positive and negative numbers.

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)*

✔ Tip for Students:
Always remember:
👉 "Keep, Change, Change"
To subtract integers:
1. Keep the first number
2. Change the subtraction sign to addition
3. Change the sign of the second number

Example:
$ 5 - (-3) $ → Keep 5, change to +, change -3 to +3 → $ 5 + 3 = 8 $

This method works every time!
