1. Breaking Down Numbers
Instead of calculating 16 × 25 directly:
- • Think: 16 × 25 = 16 × (100 ÷ 4)
- • First multiply: 16 × 100 = 1,600
- • Then divide: 1,600 ÷ 4 = 400
2. Percentage Tricks
Quick calculations:
- • 10% = Move decimal point left once
- • 25% = Divide by 4
- • 50% = Divide by 2
3. Rounding and Compensating
For 98 × 5:
- • Round up: 100 × 5 = 500
- • Compensate: 500 - (2 × 5) = 490
