Guided Notes
Key concepts students will learn:
- •
When adding a positive number, you are essentially just adding, so two plus signs can be changed to a single addition sign.
- •
When subtracting a negative number, you are actually just adding, so you can change the two minus signs to an addition sign.
- •
When the signs next to each other are the same, we add; when the signs next to each other are different, we subtract.
