Just replace your batteries with new ones beforehand. It's true that you can bring a second calculator in case OJ or drool gets into it. You can sell the calculator to someone else if you feel like it.
I've seen people walk in with four, yes, four calculators. That's how paranoid people can be.
The irony is that there are probably going to be surprisingly few problems that actually need the calculator, and even fewer that use more than basic four functions (+-*/). |
