What is -10+2 because this is really confusing to me.

-8 hope this helps btw i am a pro at this kinda stuff lol have a nice day

If you need explaining think of it asa number line. Zero is in the middle with negative numbers going down the left and positive numbers going down the right. Put a mark on -10 and move to the right 2 times. That would give you an answer of -8.

Hope this helps!
Let me know if i'm wrong.
