Pamela's Integer Scribepost

Integer Subtraction; Range (-99) to (+99) (D) 3rd Column

 Question 1:

(-29) - (-74) = 45
(-29) - (-74) = (-29) + (+74)









Question 2:

(+25) - (+39) = -14
(+25) - (+39) = (+25) + (-39)










Question 3:
(-70) - (+31)= -101
(-70) - (+31)= (-70) + (-31)









Here's a short video of Subtracting Integers on a numberline.

    I like how you have pictures to show what you're doing, also that you have a link to help people get better at removing integers. I think you should embed the video instead of having it linked. Also next time I think you should explain a little more. Overall, Good Job!
