The beauty of calculus is that you actually understand the Real World.
For example I taught my daughter factions this way.
Me: "These factions you see them? Now see these decimal points?"
Her: "Yeah I hate factions they are stupid!"
Me: "Factions are the only consistently real numbers below 1 and decimal points for the most part are made up numbers. 1/3 is 1/3 and never .3333."
Her: "I always thought it was the otehr way around."
- fao_ 10y ago... Ohhhhhh. I wish you would teach me calculus =)
- fao_ 10y agoThis... might have come out wrong. What I meant was something along the lines of: You should teach, have you considered mentoring?
- yequalsx 10y agoThe first sentence in Your last statement in your conversation to your daughter is profoundly wrong. Your daughter was not in any way made to better understand fractions by this interaction. By the way, .3333 is a rational number and therefore equal to a fraction.
- thesimpsons1022 10y agois there a reason you call them factions and not fractions?

- gohrt 10y agoYour idea did not translate into English. I think you are trying to say that most decimals we see in real life are approximations, not exact measurements, while fractions are exact? This has nothing to do with calculus, though.
