How it works
Count the zeros. The point jumps that many places: right to multiply, left to divide.
96 × 1000: the point jumps 3 places to the right, so 96000.
862 ÷ 100: the point jumps 2 places to the left, so 8.62.
Worked examples
Multiply by 1000
- How many places does the point move from 96 to 96000?
- 96 to 96000 has 3 more zeros.
- The point moves 3 places.
- So the answer is 3.
Divide by 100
- How many places does the point move from 862 to 8.62?
- 862 to 8.62.
- The point moves 2 places left.
- So the answer is 2.
Times 100
- 382 × 100 = ?
- 100 has 2 zeros.
- Add two zeros: 38200.
- So the answer is 38200.
