Grade 6 Integers Worksheets - free & printable | Worsheets library - Free Printable

Sure! Let’s solve each of the 18 problems step by step. These are all addition of three integers, which means we just add the numbers together, keeping in mind the rules for adding positive and negative numbers.

---

🔢 Rules to Remember:

- Adding two positives → add normally.
- Adding two negatives → add their absolute values, keep the negative sign.
- Adding a positive and a negative → subtract the smaller absolute value from the larger, and keep the sign of the number with the larger absolute value.

We can also add them left to right, or group positives and negatives separately — whichever is easier!
