If I recall it right, the rule is, when you subtract, you change the sign of this thing you are subtracting, then you add the changed-sign thing to the amount you are subtracting from.

(I bet the rule is not worded like that.)

So, you are subtracting +1017. Then, change its sign, from originally positive to negative now.----->>> -1017.

Then add that -1017 to -282.

I bet you know how to add two negative numbers.

If you got -1299 total, then I won the bet. - Dec 14th 2005, 09:29 AMAmanda

-282 - (+ 1017) = ?

When there are two signs in front of the same number:

If the signs are the same, replace with +

If the signs are different, replace with -

so -282-1017

For adding/subtracting, when the signs are the same, add the #s and keep the sign the same.

When the signs are different, subtract and keep the sign of the larger number, so -15+8 = -7 because 15 is larger than 8
