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.
(-6)+(-7)
(+9)+(+9)
(-4)+(+4)
(-) 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.
I like how you explained how you got the answers using number lines and integer chips! Next time you should add a video to your post. Overall, good job!
