where's the calculator?

The calculator function on this computer has disappeared. I've looked everywhere, and I can't find it. How does something like that just disappear?

Maybe you can help; what's 39 divided by 60?

Here's another question for you: Should I do the dishes?

Reason's I should

1. Its kinda my thing
2. Robin asked me to, and she made me yummy lasagna tonight
3. If I don't, ants will descend upon our kitchen
4. Jesus would

Reasons I shouldn't

1. It's almost 10:00, and I'm physically tired and mentally exhausted from grading tests
2. I still have to take a shower (I played basketball after school today)
3. If I leave them, Robin will probably do them tomorrow.
4. We can eat off of paper towels for a couple more days.
