I know this may seem strange, but it's popped up a few times in school. Someone has a calculator that has dead batteries, so they just go out and buy a new one, as opposed to replacing the batteries in it. Are calculators really that disposable? Considering that I'm speaking of scientific calculators, they might go for like $15. That's what Amazon brought up for the prices of the calculator I use, and the Texas Instrument brand that's common around high school. Price for batteries? Around $4, up to $10. So people think that the inconvenience of figuring out what battery you need, buying it, opening up the calculator, and replacing the batteries is enough to justify them buying a new calculator. I've used the same calculator for over three years, and replaced the batteries once. I tell you, it was much easier than finding the same calculator, or having to learn how to use a new one. Does this make me crazy? Or is there anyone out there who agrees?
