What is -2 + 6 + 1=1 + 6 + -2

Yes they're equal

Step-by-step explanation:

Umm, I'm not sure what we're supposed to solve here but I'm assuming it's to see if the two equations are equal.

We can simply solve them as --> -2 + 6 + 1 -->  -2 + 6 = 4 -->

4 + 1 = 5

Then 1 + 6 + -2 --> 1 + 6 = 7 -->

7 + -2 = 5

They match up and thus, they're equal
