Question: i need Math Help with integers its short?
When you add to integers how can you decide wether their sum will be positive,negative,or zero?
Answer: Just add them together, and see what number they come out to.
If you add a positive with a negative then you take the negative number away.
e.g. 5+-4 is the same as 5-4 which =1
If you add two positives you always get positive.
e.g. 10+10=20
If you add a negative and a negative you get a negative
e.g. -4+-4 is the same as -4-4 which =-8
