100 x 60 = 6000
100 times 60 is 6000. Drop the zero from 60 to get 6, then put back the three zeros the two numbers carry between them. Six thousand is the total.
100 × 60 = 6,000
Adding 100 to itself 60 times gives the same answer.
How 100 x 60 reaches 6000
100 x 60 = 6000. Reduce both numbers to their leading digits, 1 and 6, and multiply to get 6. Then hand back the zeros: one from 60 and two from 100, three in total. A 6 with three zeros is 6000.
Sixty is the clock number
An hour holds 60 minutes, so 100 hours is 6000 minutes. A minute holds 60 seconds, so 100 minutes is 6000 seconds. Turned around, 6000 seconds is 1 hour and 40 minutes, because 3600 seconds fill the hour and the remaining 2400 seconds are 40 minutes. Most real uses of this product are time conversions of that kind.
Ten times a smaller sum
6 x 100 is 600. Using 60 instead of 6 multiplies the answer by ten, and that is the single extra zero in 6000. If you are converting minutes and the answer looks like 600, check whether you used 6 where you meant 60.
