What is 16-10/2+10+11. what are the steps to solve this? i know pemdas bit i'm confused

So i can totally see where your confused. At first i was confused myself. 
But i got now :)

16 - 10/2 + 10 + 11

So the first step is to divide. Since PEMDAS says to divide...
We divide our -10 and 2 
-10/2 = -5 

Now lets set up our equation again. 
16 - 5 + 10 + 11 

Our next step is to add! Just like PEMDAS says to..
soo add 10 and 11 
10 + 11 = 21 

Wait!! we aren't finished adding yet! 
Set up our equation once more. 
16 - 5 + 21 

Now add -5 + 21!!
-5 + 21 = 16 

Now all we have left is 
16 + 16..

So... 16 + 16 = 32! 

Your answer is 32

Good Luck!

No because if you do the higher number minus the lower number you will get a positive. if you do it the other way around you will get a negative number
