Mr. Israel Ramirez demonstrates how 1 is equal to 2 through an

algebraic proof. He is really showing why dividing by 0 is not a

valid operation and he is also showing the general use of operations

in proofs. Questions this video answers Why is dividing by zero an

invalid operation? What are some mathematical operations that are

not allowed to be performed on an equation? Can I perform any

operation on any equation? Can I multiply both sides of an equation

by any number I chose? Can I add any number to both sides of an

equation? Can I subtract any number to both sides of an equation?

Can I divide both sides of an equation by any number I chose? What

other ways can I write the number zero? What does zero look like?

Mr. Ramirez does a nice job laying out all the steps he is taking. I like that he wrote them along the side as he solved the problem. The video was very easy to follow. I like that he shows us that any operation can be performed as long as it is balanced on both sides. It is a very interesting problem to solve and it is really cool to see how one could equal two. Overall, this is a really good video.

In this video, I like that Mr. Ramirez write this with somewhat of a formal proof layout, naming the steps he took on one side of the math. I also like that the video works so well without words. Though there is no speaking, it still is able to communicate the idea Mr. Ramirez was trying to get across.
