How Many Marbles Are Left?

Rita has two boxes of 300 marbles. From Box A she gave away x marbles.
From Box B she gave away y marbles. How many marbles does Rita have left?

Let me see.

There are 600 marbles in all (two boxes with 300 marbles in each box).
Rita gave away x marbles from Box A and y marbles from Box B.

So, in all she gave away (x + y) marbles.

I say that the total number of marbles Rita has left is
600 - (x + y).

You say?

Good. Another problem solved. Another one to boast about.
