Question

Which number line can you use to simplify 2+(-8)?

Answer 1

The last one is the correct answer because it starts at two and if you subtract 8-2 and the and swear is six, and then you add that (-) sign. Or start at two and go backward eight times :)

Answer 2

The second line is the correct answer. 2+(-8)=10 because the parathese makes it positive so 2+8=10
