A subtraction fact is a basic problem like 9-4=5. Knowing these by heart is a key skill. šÆ **Your Ninja Mind-Tricks:** 1. **Counting Back:** For subtracting small numbers (-1, -2, -3). For 8-3, think "8... 7, 6, 5". The answer is 5. 2. **Using Addition Facts (Fact Families):** This is your most powerful tool! For 10-7, think in your head, "What plus 7 equals 10?". You know 3+7=10, so 10-7 must be 3! 3. **Counting On to Find the Difference:** Best for numbers that are close together. For 9-7, think "7... 8, 9". That was 2 steps.
