The new SAT eschews the simple and time-honored term “Arithmetic” in favor of the clunky “Numbers and Operations.” Not that it really matters, since both cover the exact same thing, and this gave us the chance to use the word eschews, which has nothing to do with teeth or chewing. Eschew means “to avoid,” and as you know, the SAT tends to eschew simplicity a lot. Hence: Numbers and Operations.

The nifty table of contents above shows all the Numbers and Operations topics. For the new SAT, you should know this stuff so well you barely have to think about it, especially since a number of these will resurface in algebra questions.
