On a number line, 10 to the left from zero followed by 7 to the
left takes you to 17 to the left, or -17.

Stand on the number line at the position of the first number, namely -10. Now you move 7 numbers, but you must go to the left because it is -7.

The other way to look at it is that you NEVER subtract, you always add the negative, thus:

(-10) - 7 is the same as (-10) + (-7) and it should be fairly clear that the sum of these two is -17.

Hope that helps.
