24 x 100 = 2400
24 times 100 is 2400. The fastest route is 2500 minus 100. It is also the exact number of hours in 100 days, which is where most people meet this particular number.
24 × 100 = 2,400
Adding 24 to itself 100 times gives the same answer.
24 x 100 without writing anything down
Two routes, both quick. Split the 24: 20 x 100 = 2000 plus 4 x 100 = 400 gives 2400. Or round up and take a hundred back off, because 25 x 100 = 2500 and 2500 minus 100 is 2400. The second route is faster once quarter-hundreds are automatic.
2400 is 100 days
A day holds 24 hours, so 24 x 100 is the hour count of 100 days: 2400. That is the thing this product is most often a quantity of. Counted the other way, 100 days is 14 weeks and 2 days, so 2400 hours is a full quarter plus a fortnight.
Where else the digits 2400 show up
- In 24-hour military notation the end of a day is written 2400 and read as twenty-four hundred.
- 2400 bits per second was a standard dial-up modem speed, one step up from 1200.
