Using a Numberline to add Intergers








a) (+2)+(+3)= +5








b) (-4)+(-2)= (-6)








c) (+3)+(-2)= 1








d)(-5)+(+4)= (-1)



Positive numbers move right
Negative numbers move left

A Numberline can go Vertical ( up and down)


Here's a good video about adding intergers with a numberline

  3. Great post, Mark. The video and pictures looked very nice. Maybe next time you should put a little more space at the bottom. But everything looked great.

  5. Great post mark but next time you should leave the question color black because for the last one the question was red and the next word is red so it's kind of confusing but overall the pics and video were great.
