6 x 100 = 600
6 times 100 is 600. Multiplying by 100 shifts the 6 two places left and two zeros fill the gap. The same 600 comes out of 60 x 10 and out of 3 x 200.
6 × 100 = 600
Adding 6 to itself 100 times gives the same answer.
How to do 6 x 100 in your head
Multiplying by 100 moves every digit two places to the left. The 6 leaves the units column for the hundreds column, and two zeros fill the space behind it. That is the whole method, and it holds for any whole number: 7 x 100 = 700 and 8 x 100 = 800 take the same single step.
The same 600 from other pairs
600 is not only 6 x 100. Move a zero from one side to the other and the product stands still: 60 x 10 is 600, and so is 3 x 200. Add a zero to the 100 instead and you get 6 x 1000 = 6000, which is the calculation this one is most often confused with.

| 6 x 1000 | 6000 |
What 600 counts
- 600 minutes is exactly 10 hours.
- 600 seconds is exactly 10 minutes.
- Six sealed boxes of a hundred: envelopes, cards, sheets of paper.
- 600 metres is one and a half laps of a 400 metre track.
Splitting 600 evenly
600 has 24 whole-number divisors, which is generous for a number that small. It divides with nothing left over into groups of 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200 and 300. That is why 600 turns up so often in seating plans, batch sizes and split bills.
Next steps in the same family: 100 x 5 = 500 and 100 x 10 = 1000. Everything else is listed on multiplication answers.
