How many times can you subtract 10 from 100?

Only once. The next time you’d be subtracting 10 from 90.

Once because as soon as you subtract 10 from 100 it now becomes 90 therefore you wouldn’t be subtracting 10 from 100 anymore you would be subtracting 10 from 90 :) ;)

The answer is 10, this is because 100 is a single entity, the 90 is still part of the 100. If you want to use this as a trick question where the words are extremely ambiguous …then fair enough with your answer of 1. But if this question is set using a mathematical framework, then the answer is most definitely a 10. This of it this way, if you have 100 oranges, you can keep taking 10 away from it 10 times. This is because all the multiples of 10 – 20, 30, 40… till 100 are still part of the 100!
