Add 2 mn, -4 mn, 8 mn, -6 mn

0 mn

Step-by-step explanation:

First you would write the equation 2+(-4)+8+(-6)

Now let’s solve starting from the left.

2+(-4) = -2

This is the equation so far: -2+8+(-6)

Then you would solve the right side 8+(-6) = 2

Now we have -2 + 2 which equals 0.

PS. You can also do in another way like 2-4+8-6. It’s the same method and concept.

Hope this helps!
