Felipe cut away 1.98 meters of rope. before that, he had 5 meters of rope. how much does felipe have left

So, for this problem you need to subtract the amount of rope that Felipe cut away. 

5m - 1.98m= 3.02 meters of rope left.

Possible (this is only if your Professor is trying to be tricky) Technically Felipe still has 5 meters of rope, but it is in two pieces of different lengths. I think you could make an argument for either answer. I chose the answer that I thought was more likely correct.

My
Now, Felipe has 3.02 meters of rope left.

What am i doing here. add?
