## 💡 Key Concept Reminder:
-
“More than” →
Addition (+)
-
“Less than” →
Subtraction (–)
- When the starting number is missing,
reverse the operation:
- If it’s “X more than ___ = Y”, then ___ = Y – X
- If it’s “X less than ___ = Y”, then ___ = Y + X
This helps build foundational understanding of inverse operations — very important for future math!
