Math: Integers

      In Math we are learning how to add, subtract, multiply, and divide integers. So, ill just tell how you can do it. For adding integers you just have to add normally. Like this question (+4)+(+5)=+9. Unless you have a question like (-5)+(+2) . You just subtract -5 and +2 which equals -3, you have to watch out which number is higher and its sign. Subtraction is pretty easy you just add the opposite. (-5)-(+6) à (-5)+(-6)= -11. Multiplying and Dividing are the same. If you have questions that are POSITVExPOSITIVE it equals positive, and NEGATIVExNEGATIVE equals positive. So, if they are the same sign its positive. When the sign is POSTIVExNEGATIVE or the other way around its always NEGATIVE! So far integers are one of the easiest units in math that I have done.  Thanks for listening
