In this video, we examine how you know when you can multiply two matrices, and what the size of the product matrix will be.

In this video, we learn how to multiply two matrices that are different sizes.

In this video, we practice calculating how volume and surface area would change as we change the linear dimensions of 3d figures.

The sum of the exterior angles of a polygon is discussed in this video. We derive the rule, solve practice problems, and then at the end we look at an interesting relationship between the sum of the INTERIOR angles and the sum of the...

In this video, we derive the rule for the sum of the interior angles of a polygon: 180(n-2). The formula is derived by taking the number of sides, subtract two (to find the number of triangles), and then multiply by 180. At the end of...

In this video, we will dilate figures on the coordinate plane when the center of dilation is not the origin. The first example is a standard dilation (enlargement) with a non-origin center, and the second example gives you both the...

Learn how to use the correct angle rules to solve this question.

In this video, How to Calculate Percent Change from Math Defined, Mrs. C walks you through step-by-step examples using real-life situations you can relate to — like video views, price drops, and even a jellybean guessing contest. 🍬

In this video, I’ll show you *two easy methods* to determine whether two ratios (or even a whole table of values) are proportional: ✅ *Simplifying Ratios* – Reduce each ratio and compare! ✅ *Cross Products Property* – Multiply across and...

Professor Thomas Weber honors Simon Price, his college advisor at Lady Margaret Hall, Oxford, remembering him as one of the most supportive mentors he could imagine. Weber recalls arriving at Oxford in 1996 to study ancient and modern...

Anxiety and Stress have major effects on memory. The Weapon Focus Effect is one model, which considers the impact of a high-stress-inducing object, such as a weapon, on an individual's ability to recall information later.

To determine the perimeter of a triangle, you simply add the lengths of its three sides. Whether it’s a scalene triangle with different side lengths, an isosceles triangle with two equal sides, or an equilateral triangle where all sides...

Explore the innovative world of Andy Cavatorta, where robotics merge with art to create unprecedented musical experiences.<br/>

Learn how the speed of an ideal fluid changes when it flows through a pipe with varying cross-sectional areas. In this fun and engaging video, we apply the continuity equation for volumetric flow rate and solve a problem step-by-step....

Video production is hard, so I used the latest AI technology to write, narrate, and edit videos in my own style. Everybody is suddenly worried Artificial General Intelligence or AGI will replace humans in the near future, so let's take a...

This video teaches how to read and spell words with soft c. We learn soft c is followed by an e, i, or y and compare it to hard c.
