You laugh but if you ever take a college physics class you’ll appreciate having the idea of being overly careful of your units drilled into you.
Or anything else really
It’s hell to try to understand something someone gave you if they don’t label things properly. It’s like “I can see there is a number here, but what the fuck does the number mean”
In another thread I was laughing about how U.S. utilities charge for electricity by the kilowatt hour, but charge for piped natural gas by the “therm,” which is 100,000 BTUs. BTUs are the energy required to raise 1 pound of water by 1 degree Fahrenheit, like a shitty imperial calorie.
Confusingly, most gas appliances are marketed as being a certain number of BTUs per hour, but people often omit the implied “per hour” when talking about them, and will talk of their 12,000 BTU stove burner or 30,000 BTU water heater.
Talking through residential energy use without having a solid command of what unit means what would be confusing.
Factor label conversions. They get really complicated in chemistry as well.
Considering this kid didn’t learn which side of the number the dollar sign goes on, maybe they shouldn’t be making fun and should pay more attention.
You’re of course correct in English, I just wanted to share that the currency sign goes after the value in many other languages, so it’s an easy mistake for ESL people to make.
Don’t some English speaking countries put their dollar sign after? I thought at least one of CAD or AUD did
ETA: I dunno why but this comment is bringing me a lot of joy. I have been corrected by three people now without a single downvote. I asked an honest question, and got honest answers with no backlash. Imagine seeing this question on Reddit
My calculus teacher made us write our answers in complete sentences. I regret not putting bees in his car.
Bananas
A dollar bill is approximately 0.876 bananas long, and 0.372 bananas wide, and has a surface area of about 0.326 square bananas.
So, $95 is about 30.96 square bananas. Might as well round up to 31 square bananas.
Feel free to check the math yourself:
Edit: In terms of banana market value, that is always fluctuating, but if a banana is duct taped to a wall, $95 is still not going to get you even one banana.
What are we describing when saying a square banana?
In good faith I understand this as: the square of it’s length.
But I prefer to interpret it as, a banana squashed until it is 1atom thin and shaped in a square (which to my imagination, is an enormous square)
Yes, I’m going by the square of its length. Though I like your way of thinking 🍌
It’s one square banana Michael, what could it measure? 10 dollar bills?
Units are important. The teacher is right.
380 quarters
