Question

Another day for brainliests if u answer my questions right :D

Answer 1

Because they will give you the same answers lol

Answer 2

You use keep, change, change so you’ll get -15+6.

You will get the answer -9 for that one. The second one is 15-6 which equals 9.

They are similar because for both of them, you are taking 6 away from 15. The only thing that is different are the signs.
