No matter how you slice it, there are some tricks on the SAT. Tricks can mean anything from the little details (did you know that ‘0’ is an even integer?) to, well, stuff that is just plain tricky. For the first variant of trickiness, try the following: How many consecutive integers are from -5 to […]

Every now and then you’ll see a cube on the SAT in which a dotted line connects vertices on other ends of the cube. Your job is to find that line. This usually requires that you have to use the Pythagorean theorem twice (talk about cumbersome!). Luckily, I’m here to the rescue. When ever you […]

Paul and Mike are painting their backyard fence. If Paul takes 6 hours working at a constant rate to finish the fence, and Mike takes 4 hours, how long would it take them working together to finish painting the fence? This question is called a work rate question and it actually, once in awhile, comes […]

Every now and then, the SAT uses a property of triangles that throws most for a loop. I like to call these triangles “Extreme Triangles”. So let’s imagine an isosceles right triangle. Remove the hypotenuse and you’ll get two line segments that meet at a right angle. Now, take the vertical segment and pull it […]

Functions can be daunting. Where do you plug in the number? Do you plug the equation in the function or the function in the equation? All of this might make you just want to unplug from the SAT altogether. But don’t despair. Let’s do a quick introduction to functions before ending with a challenge question. […]

The first thing you got to know is that there are four quadrants in a coordinate plane. What’s wacky is how these quadrants are arranged: A good way to think of it is to imagine yourself on a cross-country trip in which you start off in New York (the northeast = quadrant I), drive on […]

Probability strikes dread into almost everybody. Couple that with the fact that many probability questions are convoluted word problems so that even the most confident math-o-phile is quaking in her boots. But before we get to the dread-inducing question a quick rundown. The magical, make-your-life-a heck-of-a-lot-easier probability equation: # of possibilities you are hoping to […]

Who else is excited about the World Cup? We watch all the games here in the office. And, yeah, we were sad to see the U.S. go home. What a game, though. (Tim Howard is our hero.) In honor of the upcoming World Cup finals, we put together an SAT math/World Cup soccer mashup video […]

Series of numbers Sometimes the SAT will ask you to notice a pattern in a sequence of numbers. -3, -1, 1, 3, 5 These numbers form what are known as a sequence. The one above is known as an arithmetic sequence, because each number increases by a fixed sum. So if we were to continue […]
