This video is chapter 7 in my series on special relativity, and it covers the idea that some things AREN'T relative: there IS a sense of absolute length and absolute time, which can be agreed upon from all moving perspectives (as...

Imagine a group of people. How big do you think the group would have to be before there's more than a 50% chance that two people in the group have the same birthday? The answer is - probably lower than you think. David Knuffke explains...

You've found Leonardo da Vinci's secret vault, secured by a series of combination locks. Fortunately, your treasure map has three codes: 1210, 3211000, and. . . hmm. The last one appears to be missing. Can you figure out the last number...

New ReviewIn this math video, we will learn how to write the equation of a quadratic function given three points. We begin by recognizing that two of the given points are zeros, or x-intercepts, and use them to write the quadratic in intercept...

New ReviewIn this YouTube Shorts math video, we quickly show how to simplify a radical expression and write it in simplest form. We will review why simplifying requires rationalizing the denominator using the conjugate to create a difference of...

New ReviewIn this video I take a trigonometric expression and multiply it by another trig expression.

New ReviewIn this video we will explore and Easy vs Hard approach to identifying the inverse of a rational function.

New ReviewIn this video I am going to work through a problem that is easy to factor as well as one that we cannot factor through rational numbers so will need to use the quadratic formula

New ReviewIn this video, I demonstrate simple methods for solving linear equations containing fractions, specifically focusing on two step equations. We explore how fractions can show up in our equations and how to use problem-solving strategies...

New ReviewWhen you are trying to solve a system of equations there are three tips that I want for you to remember.

New ReviewIn this video we are going to take a look solving radical equations one that is a simple one and one that is more advanced

In this shorts math video we will answer a standardized math test question where we simplify a numerical expression. We will understand that we need to simplify the expression in the parentheses FIRST. We will review that we need to...

In this shorts math video we will write & solve a real world system of linear equations. We will define our variables and use the information provided to write two linear equations in two variables. We will understand that the sum of...

In this math video we will review how to simplify a polynomial expression. We will begin by clearing the parentheses using the Distributive Property. We will review that you multiply each term inside the parentheses by the factor...

Write the equation of a circle given the center and the radius.

In this math video we will discover polynomial subtraction. We’ll subtract two polynomial expressions using the vertical stacking method — line up the like terms and subtract each set of like terms.
