Probably the most common challenge that I see my students struggle with is understanding and writing out mathematical proofs. Although most higher level college math and computer science courses rely heavily on proofs, there aren’t many courses that really prepare students before they’re thrown off the deep end. I wanted to discuss some tips and tricks that’s helped my students become more comfortable with proofs, and some steps you can take to prepare yourself if you are planning on taking such a course.

If we would like to do so by laying as little road as possible, how do we do it? In this blog post, we will use Calculus to tackle a special case of this optimization problem.

Mathematical induction is a common and very powerful proof technique. At its core, it’s an appeal to an intuitive notion that Induction proofs often pop up in computer science to proof that an algorithm works as intended (correctness) and that is runs in a particular amount of time (complexity). In this tutorial we’ll break down a classic induction problem in mathematics, and in the next post we’ll apply the same techniques to a classic computer science problem. As a warmup we can look at a classic example used to teach induction, namely the proof that the sum of integers from 1 to *n* is equal to

## An Insider's Tip to Prepping for the SAT Math Section: Plug in Numbers

Posted by Daniel Pa on 3/11/19 6:53 PM

Preparing for both mathematics sections on the SAT can be a bit intimidating. You can’t expect yourself to know every topic that might come up, and the time limit adds to the stress. Much more efficient than trying to learn everything you might come across is to start with what you have already learned in high school and use examples to apply it more widely in the SAT. The most classic sort of example is what teachers have been drilling for ages: plug in numbers. However, mathematics is all about generalizing rules and strategies, so I want to talk about how to expand plugging in numbers to the art of creating your own examples.

**How do you feel about math?**

Let’s take a minute to think about math and how we feel about it. Good memories or bad? Or both? If I were to draw an analogy about math and anything else, it would be a foreign language. You can’t forget what you learned in arithmetic and expect to do well in algebra, just like you can’t forget how to conjugate French verbs and expect to write a full sentence. Math requires a great foundation and, once that foundation is built, everything else comes after. I am here to help you build that foundation. I am here to tell you that math isn’t supposed to be scary or cryptic or over your head and I’m not just saying this because I am a tutor, I am saying this because I have been there, staring at a problem and blanking, putting the pencil down, getting scared, when another second spent ‘braving the storm’ made all the difference.
