**Essential Question**: How can i add integers?

 * 1.** When You add two integers, how can you decide whether their sum will be positive, negative, or zero?
 * ans: When both numbers are negative the answer is a negative. When both numbers are positive the answer will be positive, but when both numbers are opposite numbers, the answer will be zero. And also when the numbers are both negative and positive, it would depend on the larger number.


 * 2**. Describe how to add any two integers:
 * ans**: If both numbers are positive then just add them. But if the numbers are negative, add the numbers and then put a negative sign at the top/side of the numbe

b) zero has no opposite 0 c**) If the number is a negative then take way the number sign and keep the number -12 12
 * 3**. Explain how you can find the opposite of a number. Use the following examples to illustrate your explanation.
 * a) If a number is positive, then put a negative sign. 7 -7

In this investigation I learnt how to add and subtract integers. I also learnt what opposites are. I learnt how to use a number line and a chip board and how they help you answer simple integer problems. On the number line I understood how to add on numbers to reach to your answer. Also knowing that even if the numbers are switched around it would still have the same meaning.
 * Summary:**
