Question

I really don't know can someone help me

Answer 1

you would just divide 4 by 2 so 4 divided by 2 would =2. 
Then you would 6+2 which would = 8
So your answer is.......8

I hope that helped:)

Answer 2

               6 + 4 ÷ 2

The "order of operations" (which you learned a long time ago
if you're in high school now) says that division should be done
before addition.

So do the division:        4 ÷ 2 = 2

Now you have                6 + 2

Now do the addition:     6 + 2 = 8 .
