Integers

Integers are any whole #. To solve a problem you must look at the sign because each sign has different rules.
If the sign is + then you just add the two #s and keep the same sign. (For example -3 + -4=-7)If the signs are different then you subtract the two #s and keep the sign of the bigger #. (For example -2 + 7=5)
If the sign is - then you must change the - to a + and put the opposite sign in front of the second #. Then use the addation rules. (For example -5 - -7 chage to -5 + 7=2)
If the sign is x then you multiply the two #s and if the two #s have the same sign then you would multiply the two #s and there would be no negitive sign. (For example -6 x -5=-30) Or if the signs are different then there will be a negitive sign in front of your answer after you multiply. (For example 4 x -6=-24)Also if there are a even # of x signs then there will be no negitive sign and if there is an uneven amount of x sign then there will be a negitive sign.
If the sign is / then you can use the same rules as when you multiply.
Now you can do any problem with integers!
