Let's learn how to factor quadratics where the leading coefficient isn't 1 without guessing and checking.

In high school, I didn't realize difference of two squares literally meant "what's the difference between these two squares?"
Here's how we can visualize x²-y²=(x-y)(x+y).

It's Mental Math Monday! How would you mentally calculate 62-28? Are you thinking about it as "what's the difference?" or "take away"?

This is one of my favorite fraction division videos I've made so far.
We can make sense of fraction division if we think about it as a missing factor in a multiplication problem.

NEW: There’s a disaster unfolding in Alaska right now. And no major network is covering it.
The remnants of Typhoon Halong battered western Alaska overnight. Homes, with people in them, have literally been swept into the Bering Strait.
At least 20 are missing. No comment from any federal agency.
