# SAT Tip of the Week: Hotline Bling Is an SAT Thing

It’s Hip Hop Month in the “SAT Tip of the Week” space, where you’ll learn that that Drake is a university in Iowa (where The Motto is, of course, Veritas) as well as a rapper from Toronto, and that the Common app is a great way to prepare for your Future. So let’s start with Drake, because even if your SAT score started at the bottom, now you’re here. If you’re reading this…it’s NOT too late.

It’s been hard to go anywhere over the last year without hearing Drake’s recent hit (which was not only a monster #1 hit but also a Super Bowl commercial), so there’s a fair chance that as you drive to go take the SAT you’ll get Hotline Bling stuck in your head. And that’s exactly what you want.

Why?

Because, as the song goes, when you hear that Hotline Bling, that can only mean one thing. And there are several “Hotline Blings” on the SAT; recognizing them can save you plenty of time and dramatically raise your accuracy.

Hotline Bling: SAT Math
Positive vs. Negative
For example, on the Math sections, you might see a statement like x > 0 or y < 0. Hotline bling! Greater than zero or less than zero as definitions in an SAT Math problem can only mean one thing: you’d better check the sign of your answer (positive vs. negative) because greater than 0 means positive and less than 0 means negative, and putting those definitions in problems is a huge signal that positive/negative matters.

The expression is equivalent to…
Whenever you see the words “expression” and “equivalent” in an SAT Math problem – usually “The expression (given expression) is equivalent to which of the following?” or “Which of the following is equivalent to the expression shown above?” – that’s a Hotline Bling. That can only mean one thing: you’re going to have to use the answer choices.

Either you’ll try to make the given expression look more like the answer choices (for example, if the answer choices don’t have parentheses or a denominator, you’ll need to work on the given expression to get rid of the parentheses and denominator) or you’ll be able to pick your own numbers. Consider the following example, which appears courtesy the Official SAT Study Guide:

The expression (5x-2)/(x+3) is equivalent to which of the following?
A) (5-2)/3
B) 5 – (2/3)
C) 5 – (x)/(x+3)
D) 5 – (17)/(x+3)

Notice that you HAVE TO use the answer choices here. Without them, you don’t know what to start doing with the given expression. And even with them, it may seem difficult to get a 5 all alone away from the fraction (like answer choices B, C, and D).

That can only mean one thing: this is a great problem on which to try picking your own numbers. If you were to say, for example, that x = -2 (making your math easy by setting the whole denominator of the original equation equal to 1), you’d know that you have [5(-2) – 2]/(-2+3). That means that you have -12 as the value of the given expression when x = -2, so now you can test the answer choices. Clearly A and B do not work, so then check C and D. C then equals 4 while D = -12, so only choice D spits out the right answer when numbers are involved.

Hotline Bling to the rescue – the words “equivalent” and “expression” can only mean one thing…you’d better get the answer choices involved, and there’s a high likelihood that this is a pick your own numbers problem.

Hotline Bling: SAT Writing
Singular vs. Plural
Whenever the answer choices for a Writing problem include the singular and plural form of the same pronoun or verb (“it” vs. “they”; “is” vs. “are”) that can only mean one thing: you need to find the subject and match it up singular or plural.

Homophones
Whenever the answer choices include multiple words that sound the same (they’re / their / there; it’s / its; you’re / your / yore), that can only mean one thing: the test is checking whether you know which version of the word means what. The apostrophe in those words is for a contraction (they are / it is / you are), so if you’re not trying to form a contraction, eliminate it. These problems should be quick, free points.
