Top Mental Math Hacks
- Break It Down (Chunking):
Example: 462 + 379- Break into parts: (400+300) + (60+70) + (2+9)
- Solve: 400 + 300 = 700, 60 + 70 = 130, 2 + 9 = 11
- Add: 700 + 130 + 11 = 841
- Round and Adjust:
Example: 197 + 258- Round: 200 + 260 = 460
- Adjust: 460 – 3 = 457
- Think in Complements:
Example: 1000 – 647- Add to 647: 3 to reach 650, 50 to 700, 300 to 1000
- Answer: 353
- Simplify Multiplication:
Example: 48 × 25- Round 48 to 50: 50 × 25 = 1250
- Adjust: 1250 – (2 × 25) = 1200
- Square Numbers Ending in 5:
Example: 75²- Multiply 7 × (7+1): 7 × 8 = 56
- Append 25: 5625
