Which of the following will have a negative result?

Question

Their are 3 answer to this question. They are:

1. - 8 - ( - 10 )
2. 12 - 14
3. 7- ( - 3 )

Answer 1

1. Minus a negative is the same as adding. So -8 - (-10) is the same as -8 + 10. When you have a negative added to a positive you subtract and keep the sign of whichever number was bigger. 10-8 = 2.
2. 12 - 14. Again, subtract and keep the sign of the bigger number,. 14 - 12 = 2; -14 was bigger, so the answer is -2.
3. 7 - (-3) is the same as 7 + 3, which is 10.

2 is the only one with a negative answer.
