Читать книгу SAT Math For Dummies with Online Practice - Mark Zegarelli - Страница 59

Look over the following list of 12 words:

Algebra	Arithmetic	Coefficient	Constant
Equation	Expression	Identity	Inequality
Polynomial	Term	Variable	Zebra

First of all, ignore the word zebra. I just put that one in to fill out the last row. Zebras have nothing at all to do with math. They can’t even do math.

As for the other 11 words, even though they may get thrown around a lot in whatever math class you’re currently taking, you may not be really sure about some (or all!) of them.

You could ask your teacher to explain them. In fact, I encourage you to do that. Even so, you probably won’t. After years of teaching, I get that most of my students just don’t feel comfortable asking questions about stuff that they think they “should already know.”

That’s why I’m here: for starters, to help you succeed on the SAT. But beyond this, so that the next time your teacher asks for a volunteer to identify the coefficient of the third term in the right-hand expression of the equation they just wrote on the board, you’ll be able to raise your hand with pride and confidence.
