Intercepts are one of those SAT math topics that become much easier once you understand what the words actually mean. An x-intercept is where a graph crosses the x-axis. A y-intercept is where a graph crosses the y-axis. That’s the basic idea. But the SAT can test intercepts in several different ways, including equations, graphs, … Read more
Coordinate geometry problems are common on the SAT, and two formulas can make many of them much easier: the distance formula and the midpoint formula. The distance formula tells you how far apart two points are. The midpoint formula tells you the point exactly halfway between them. Once you understand what these formulas are actually … Read more
If you’ve taken a practice SAT, you’ve almost certainly seen questions about linear functions. Why? Because straight-line relationships show up everywhere—from graphs and word problems to systems of equations and modeling real-world situations. The good news is that almost every linear function question comes back to just a few important formulas. Once you understand what … Read more
If exponents make your brain want to hit the “pause” button, you’re not alone. The good news? The SAT doesn’t expect you to memorize hundreds of exponent tricks. Instead, it relies on a small set of exponent rules that show up over and over again. Once you know these rules, many scary-looking problems suddenly become … Read more
CHECK IT Imagine the SAT asks you something like this: If xx is odd and y is even, which of the following must be even? At first glance, this might feel like one of those “Wait…what?” moments. But here’s the funny thing: the SAT absolutely loves testing whether numbers are odd or even, because once … Read more
Howdy! So check this out.. Imagine the SAT gives you a problem that asks you to add a giant pile of numbers like this: 1+2+3+4+5+6+7+8+9+101+2+3+4+5+6+7+8+9+10 What do you do? Do you actually sit there and add every single number one at a time? You could… but the SAT is secretly hoping you know a faster … Read more
Yeah I know, but hold on. Check THIS out: Stellar and indefatigable. Imagine this: You’re calling a taxi, and the driver tells you, “It’s $5 for the first hour and $3 for each additional hour.” You might think, “Cool, that’s not too bad,” but then the SAT takes this simple concept and twists it into … Read more
Unless you want to miss out on ALL THE ACTION, watch this! Amazing. Fantabulous. Can’t be stopped. Won’t be stopped. SAT math questions love to hand you a point with zero in it—like (0,3) or (5,0)—and if you know how to use that to your advantage, you can make solving equations way easier. Why? Because … Read more
Hold your horses. Check THIS out. Stellar. Fantastic. And dare I say…PRISTINE. So anyway, solving systems of equations might sound intimidating, but once you get the hang of elimination, it’s actually one of the easiest ways to find where two lines cross. If test anxiety or SAT anxiety makes these problems seem overwhelming, don’t worry—I’ve … Read more
If your child is preparing for the SAT, you may be wondering how different math questions impact their final score. Are harder questions worth more? Do all questions carry equal weight? The truth is, the digital SAT doesn’t score questions in a simple right-or-wrong manner—its adaptive format and Item Response Theory (IRT) system make scoring … Read more
