Quite easily. Think about what the difference is between the number that you want to subtract and the number that you have. E.g I have the number 10, and I wish to subtract 6 from it: 10-6. To get from 6 to 10, I need to add 4. So in this case, when I minus 6 from 10, I'm left with 4 remaining. So, 10-6=4 Or, let's say I have 16, and I wish to take away 10. To get from 10 to 16, I need to add 6. So whan I minus 10 from 16, I am left with 6 remaining. This means that: 16-10=6 This technique works for subtracting any integer (or any decimal).
