What the New SAT Mathematics Test Covers
SAT math questions rely on Algebra II and some advanced topics in geometry, statistics, probability, and trigonometry. The new SAT Mathematics section contains one 55minute section when you can use a calculator and one 25minute section when you can’t. Of the 57 questions, 45 are multiplechoice, in which you choose an answer from four possibilities, and 12 are gridins, in which you supply an answer and bubble in the actual number, not a multiplechoice letter.
Whether calculator or no calculator, multiplechoice or gridin answer, each question is worth the same except for one gridin question called Extended Thinking, which carries four times the weight of the other math questions.
Here’s a sample multiplechoice problem:

If xy – 12 = z, and the value of x is 2, which of the following must be true?
(A) z = xy
(B) y = 12 + z
(C) z = 2y – 12
(D) 2y – z = 100
Substitute 2 for x, and see which answer most closely resembles xy – 12 = z. The correct answer is Choice (C).
