subtract 10 and ouick check

1 answer

To subtract 10, you simply need to take away 10 from a given number.

For example:

If you want to subtract 10 from 25:
25 - 10 = 15

If you want to subtract 10 from 50:
50 - 10 = 40

Regarding the "quick check" aspect, could you please clarify what you mean by that term?
