Joel's Integer Scribe Post

Integer Addition; Range (-9) to (+9) (D)
Standard form is basically the same with out the brackets, but if its a positive number only put one positive symbol, not two but one.
(-2) + (+3)



(-4) + (-3)




(+1) + (+9)



(-) is the negative sign, so when you see that symbol beside the number it will be a negative number.
(+) is the positive sign, so when you see that symbol beside the number it will be a positive number.

  1. I like the way you used integer chips and number lines to make it easier to understand how you got the answer. I like how you used words to explain things to us too! Good job Joel.

  2. Good job Joel! I like how you used integer chips and number lines to show how your got your answers. I also like how you explained what Standard form is. Next time, you can improve by adding a video or a link to a game to your post.
