+or-signs properly to separate terms.
🧑🏫 Example Walkthrough
Let’s say you enter the expression:
4x + 3 - 2x + 5
Step-by-step breakdown:
- Combine like terms:
- Variables:
4x - 2x = 2x - Constants:
3 + 5 = 8
- Variables:
- Final simplified expression: CopyEdit
2x + 8
The calculator does this automatically for you and shows the result instantly.
