**Big Idea: Negative Numbers help us to model many real world situation**
 To find the difference between integers is to it has it owns ways. If you want to find the difference of a negative number with another negative number or a positive number with another positive number is easily figure out since they are both the same side of the integers. You just need to subtract the positive number like subtracting ordinary whole numbers, to subtract negative numbers is like subtracting ordinary whole number but it is just in negative. But to find the difference between of a positive number and a negative number is a different way. If you finding the difference of a positive number with the negative number you need to just make the negative number like a whole number since subtracting a negative number is just like adding a positive number. If you want to find the difference of a negative number and positive number, it is just turning the positive to a negative number since we need to subtract the positive number by a negative number
 * ESSENTIAL QUESTION:**
 * How do I find the difference between integers? **

=
**1. Write a strategy for finding the difference of two integers. Be sure to consider all possible combinations of positive integers, negative integers, and 0. Verify your strategy by finding the following differences** ======

=
We are looking for the difference between -5 and -3, just like how we find the difference of 5 -3 is 2. So if we do from the opposite side, which is -5 - -3, the answer will be the opposite of itself which is -2. ======

=
A) One of the numbers is Negative and the negative number is higher in absolute value than the other (-6 + 3 = -3)======

=
C) If only 1 number in negative and it is place in as the second number, the negative number is just adding up the number because subtracting a negative is like adding a positive number. ( +8 - -12 = -4) ======

=
Integers are like numbers but are like having an opposite side. Addiction and subtraction are related by is like a opposite world like adding 5 and 5 is 10, in the negative world -5 +-5 is -10. They are related by doing calculations that will end up a opposite answer. ======

=
Using the integer line, the find the absolute value is to move the exact same unit but in the other direction. If you move to the right 7 unit, to find the absolute value I to go 7 unit to the left side. ======

=
**TO modelling addition and subtraction of integers is a much more difficult way just to add or subtract normal whole numbers. Finding difference between integers are little bit complex, is also the same thing adding integers. Learning how to find sum and difference of integers and how it works it is like everyday life. It is like measuring how deep the ocean is (-238 feet from land) or measuring how high a mountain is (+386 feet from land). WE did also learnd the inverse operation, the operation that can undo each other. Adding and subtracting are inverse operation. How we learnd all this method of to add and subtract integers are a math process that we do to describe elevation and measures.** ======
