INTEGERS - HELP!!!
If you're having trouble with integers, here's some help:

Ex: ** 5 + 8 = + 13 ** **Different Sign = Find the difference (subtract) and keep the sign of the bigger number.** Ex: ** 47 + ( - 18 ) ** becomes ** 47 - 18 = 29 ** **- 35 - ( - 23)** becomes **- 35 + 23 = - 12**
 * //Adding and Subtracting Integers://**
 * When you have two signs next to each other (with no numbers in between) Rewrite the expression to simplify it:**
 * + + ** = rewrite the problem with ** + ** Ex: **3 + ( + 10 )** becomes ** 3 + 10 **
 * + - ** = rewrite the problem with ** - ** Ex: ** 12 + ( - 9 ) ** becomes ** 12 - 9 **
 * - + ** = rewrite the problem with ** - ** Ex: ** 5 - ( + 7 ) ** becomes ** 5 - 7 **
 * - - ** = rewrite the problem with ** + ** Ex: ** 26 - ( - 8 ) ** becomes ** 26 + 8 **
 * After you rewrite the expression, follow these rules:**
 * Same Sign = Add them together and keep the sign. **
 * - 14 + ( - 20 ) ** becomes **- 14 - 20 = - 34**

Follow these simple rules: **Same Sign = The answer is always positive (+)** Ex: ** 5 x 3 = + 15 ** **Different Sign = the answer is always negative (-)** Ex: ** 2 x ( - 8 ) = - 16 **
 * //Multiplying and Dividing Integers://**
 * -7 x ( - 9 ) = + 63 **
 * 24 / 6 = + 4 **
 * - 45 / - 9 = + 5 **
 * - 10 x ( + 3 ) = - 30 **
 * 56 / - 7 = - 8 **
 * - 72 / 8 = - 9 **
