600 x 100 = 60000
600 times 100 is 60000. Multiplying by 100 shifts every digit two places left, and 600 already ends in two zeros, so the answer ends in four of them.
600 × 100 = 60,000
Adding 600 to itself 100 times gives the same answer.
The working
Multiply the parts that are not zeros first: 6 x 1 = 6. Then count the zeros. 600 carries two, 100 carries two, so the answer carries four. Put them behind the 6 and you get 60000.
Three pairs, one answer
You can slide a zero from one side of this calculation to the other without changing the product. All three of these come to 60000:
- 600 x 100
- 60 x 1000
- 6 x 10000
That is why 6 x 100 = 600 is the fact worth knowing first. Once you have 600, every version of this question is zero counting.
What 60000 usually counts
60000 divides by 12 with nothing left over, so a yearly figure of 60,000 is exactly 5,000 a month. 60,000 seconds is 16 hours and 40 minutes. It is not a square number: 244 squared is 59536 and 245 squared is 60025, so the root falls between them. That sets it apart from 40 x 1000 = 40000, which is 200 squared exactly.
The one people mix it up with
600 x 1000 is 600000, ten times larger. The tell is in the multiplier: two zeros in 100, three in 1000. If the thousand is what you meant, 100 x 1000 shows the same zero rule one size up.
