Thanks, CPhill! So, essentially, when you use synthetic division, remove the variable, execute long division on each coefficient by the factor you are testing, and reinsert the variable with respect to each part's powers? Or am I still wrong? Because I'm still quite lost with synthetic division. I mean, I would use long division, but no, we have to use synthetic division because it makes that much of a difference in the long term.
Don’t know where this is from, but their phrasing is annoying. Ok, here goes.
When it’s talking about the square being palindromic, it means it is the same forwards and backwards, e.g. 1794683864971. As for the number base stuff, I have no clue. Speaking of which, what language are you using? It seems like base code, which is only really useful to my brethren, the Hackers.
Sorry I couldn’t be much help! If you reply w/ more info, I’ll try to follow up.
The placement exam is essentially their way of seeing if you are smart enough to take the class. Think of it as a stuff of security for their money. This way, if you aren't smart enough, they won't waste money. I would recommend Khan Academy for practice. They also teach fixing, which I saw you were interested in.
