Elina,

I’m not sure if there’s a syllabus online, but what you’ll need
to know is set forth in the Official SAT Study Guide. Good luck.

Mina,

Two is the lowest prime number. The ones you should know for
the SAT are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, and 37.

Betty,

Sorry for the delayed response. Your questions are good ones that are on topics that confuse a lot of people.

Zero is considered an even number that is neither positive nor negative.

Picture a bank account with no money in it. It doesn’t have a positive balance and it doesn’t have a negative balance. It has something in between — a zero balance. (Think of zero as the number that separates the positives from the negatives.)

To help with the even-odd confusion, think of a number line.

. . . -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, . . .

You’ll notice that the zero falls in line with the pattern of even numbers.

I hope my comments help. Good luck.

This is sort of off topic, but I didn’t know where else to ask this. What about zero? Is zero an even number? Or is it odd, or neither odd nor even? Is it positive, negative, or neither? I’ve taken some practice tests where I have stopped and wondered this, but I never figured it out.

Thanks,
