This is why Algebra drains your brain

[00:00:00]This is why algebra drains your brain.

[00:00:02]You're going to love this one. Here, it's introducing unknowns, you know, the letters using maths. But first, there's a criminal story. The motorbike robber.

[00:00:11]Then somehow Einstein shows up and how he was infected with the love of mathematics.

[00:00:16]Which then leads to a riddle. Here, you're going to meet John and David. By the way, John is going to be called X.

[00:00:23]Then we finally get an equation and the expanded version on the right-hand side.

[00:00:27]And wait, they also call the equation a creature.

[00:00:31]And using this equation, we're supposed to find the identity of the criminal.

[00:00:37]Then he goes into solve the equation by, and I quote this, simple observation. What a drainer.

[00:00:44]The idea here is simple. A letter, or the unknown, is called a variable.

[00:00:50]Solving an equation means working out what the variable equals. And how you do that depends on how the equation is set up. That's it.

[00:00:58]Anyway, I really want to know if you've ever read a maths page and totally forgot what you were even learning.
