11. Hint: If you don’t see a sign in front of a number, don’t panic! No sign means it is a positive number!
12. Addition Rules If the signs are the same, cross them out and pretend they are not there and add as you normally would. After adding the numbers together, place the sign in front of the answer.
14. Rule # 2: If the signs are different, pretend they are the same and subtract the smallest number and add the sign of the largest number to your answer.
15. For Example: Subtract the numbers normally and add the sign of the largest number: 5-3=2 add sign =-2
