Binomial Trinomial Multiplication

https://annasmathpage.com In this video, I show how to multiply (x+1)(x+2)(x+3) using the Mortensen Math Basic Operations Kit. Instead of jumping straight to symbols and rules, we build this expression step by step using blocks so you can see what each part represents. This makes it easier to understand where each term comes from and why the final expanded expression looks the way it does. This is especially helpful if algebra has ever felt abstract or disconnected. When you can physically build the expression, the algebra starts to make sense. Quick note: the image and audio quality in this video aren’t great. My setup was being a bit difficult that day, but the math itself is solid, and I wanted to share it anyway. If you’re learning algebra or helping someone else learn it, I hope this gives you a clearer way to think about multiplying expressions like this. Thanks for watching. #maths #algebra #education #mortensenmath
