Operation:Interger

Today we are working on intergers and how to do operations on them. Of course, you learned about operations in my previous lessons. This time, however we are not just adding or "subtracting", we're going the whole nine yards. Of course we start with addition. Addition is different for negative instead of the positive. Like posotive, negative is just smashing together two negatives to make an even greater negative. Here's an example:

-5+-6=-11

Very simple, if you're doing the same signs. Now we are getting a little more challenging with different signs. Adding with different signs are hard. There is a rule for doing these type of problems, that is add them together and keep the sign of the larger number. Here is an example:

5+-6=-1

This kind of reminds me of subtraction except keeping the sign of the larger number. Now we will learn how to do subtraction. Subtraction does not really exist (I know that you are probaly thinking you've wasted your time in the past 5+ years learning subtraction). Subtraction does not exist because it is basically adding the opposite of the second number. Here is an example.

-5-6=_

Do the rule I just gave you and your new problem is:

-5+-6=-11

Get this and you just learned half the lesson. Now we will get into multiplication and "division". There are two rules for multiplication. They are:If the signs are the same, the answer is positive. The other rule is:If the signs are different, the answer is negative. Here is an example of those rules:

-5x-5=25

5x-5=-25

It is quite simple actually. Now it is time for division. Division may possibly not exist like it's cousin, subtraction. Anyways, division applies the same rules as multiplication exept you are dividing. Here is an example:

-25/-5=5

25/-5=-5

Very simple, Here is some imprtant key words.

Intergers-a positive or negative counting number. 5 -5

Opposite- the counter part of an interger. 6 is the opposite of -6

Extention lesson: Want to know about absolute value? Keep reading.

Absolute value is the value away from zero. For example:

The absolute value of -10 is 10(normally there are two lines around negative ten)

That is roughly absolute value for you. That's the end of the post.
