Answer: 253
Another example:
54 × 11
- 5
- 5 + 4 = 9
- 4
Answer: 594
Therefore, this trick works perfectly for many two-digit numbers.
Square Numbers Ending in 5
Numbers ending in five follow a simple pattern.
Example:
35²
- Multiply 3 × 4 = 12
- Add 25
Answer: 1225
Another example:
85²
- Multiply 8 × 9 = 72
- Add 25
Answer: 7225
Consequently, you can square these numbers almost instantly.
Multiply by 5 Quickly
Multiplying by five becomes simple with one easy method.
If the number is even:
- Divide by 2.
- Multiply by 10.
Example:
48 × 5
48 ÷ 2 = 24
24 × 10 = 240
If the number is odd:
- Subtract 1.
- Divide by 2.
- Add 5 at the end.
Example:
37 × 5
36 ÷ 2 = 18
Answer: 185
Thus, this trick speeds up everyday calculations.
Multiply by 9 Using Easy Patterns
The number nine has many useful shortcuts.
Example:
9 × 8 = 72
Notice that:
- The tens digit is one less than 8.
- The digits always add up to 9.
Similarly:
9 × 6 = 54
5 + 4 = 9
This pattern helps learners remember multiplication facts more easily.
Find 15% Without a Calculator
Percentage calculations become easier with simple steps.
Example:
15% of 80
- Find 10% = 8
- Find 5% = 4
- Add them together
Answer: 12
Likewise, this method works for many shopping discounts and restaurant tips.
Round Numbers Before Adding
Large numbers become easier when rounded first.
Example:
198 + 304
Round 198 to 200.
200 + 304 = 504
Subtract 2.
Answer: 502
Therefore, rounding reduces mental effort while keeping answers accurate.
