Adding and Subtracting Integers
By Donald Foley
If the integers are both negative they'll have a positive answer to the equation. It's the same thing with them both being positive. In fact, they're the same thing with regular addition, sort of: An odd number plus another odd number=an even number and an even number plus another even number= an even number. The only way to get an odd number is to add an odd number and an even number. The only way to get the answer to be odd/negative is to add an odd and an even/ negative and positive. It is pretty much, once you kinda dissect the two strategies they'll probably start making more since- once you make the link.
It's really simple and all you'll need is your multiplication tables,division,addition and subtraction tables memorized and to know how the things go with adding/subtracting/multiplying/dividing will go if you get 2 negatives (answer in addition would be positive) and the only way to get things uneven is if you get a negative and a positive
This is really quite easy. As easy as sitting in a chair
People often get confused with whether the integer is negative or positive. It's simple:(here's an example) -1+-1= positive, 1+1=positive and finally -1+1= negative
Portal to an alternate universe
It's sadly, but obviously not REALLY a portal to an alternate universe. I just wanted to spice things up a little. It's really just a limited and optional quiz
