# Tip #8 to Get a Top SAT Math Score (page 2)

1. 5 This question simply tests whether you know the words "consecutive" and "integer." Many students do not and wind up intimidated and having to skip this very easy question. Since you know what these two words mean, use simple trial and error to solve this question. 4 + 5 = 9.
2. C   Most people know that since 32 = 9, there is at least one answer to this question. But the term "different" is the keyword here. It is the tipoff that perhaps there is more than one answer. That should be enough to jog your brain to realize that (–3)2 = 9 also. So there are two possible answers to the question, 3 and –3.
3. E   Lots of students don't know the term "units digit" and get this wrong; since you know, it's easy. Just list the possibilities: 3, 13, 23, 33, 43, 53, 63, 73, 83, 93.
4. 31   This question intimidates many people. I know so many students who would immediately say, "I have no chance," and move on. I think that this is something the SAT is testing: can you be intimidated? Shout with me now, "NO WAY!" So once we're done with that, this is easy. Just list a bunch of prime numbers: 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 27, 29, 31 and look for two in a row (consecutive) that add up to 60. So 29 + 31 = 60. Cake, if you stay relaxed, focused, and confident.
5. C   Probably best to just find the 2 numbers. If that seems difficult, "Use the Answers" as hints, that is try –12 and –14. The two numbers are indeed –12 and –14, so I and III are true. II is a trick that the SAT tried and that we can totally predict. –12 might seem less than –14, since 12 is less than 14, but the bigger the negative number, the smaller it is; like the more you owe, the bigger the debt. This sort of trick is discussed more in Skill 43.
6. 8 There are 11 positive integers less than the number 12. How many of these are consecutive odd prime numbers? List the prime numbers that are less than 12: 2, 3, 5, 7, 11. Of these numbers, 3, 5, and 7 are consecutive odd numbers, so 11 – 3 = 8 are not.
