Ok i had a program for computer science. You take in a persons weight, a planet letter, and convert to how much they would weigh on that planet. the conversion everyone else used, say for jupiter, looked like this:
weight = weight * 0.88;
Which she gave 100's for (my teacher) i got ten points off for each time i did mine like this:
weight *= 0.88;
WTF?! I thought that was BETTER and more effecient, why would she give me points off?! And yea she went over this, but never said don't use it WTH?!
