I wish this was longer. Love the way you actually taught this.

I had the same question as the student in the video about the left bracket which goes on the stack, but I think I understand now; basically the left bracket 'has a precedence' which other operators compare their own precedence against, but the left bracket ignores its own precedence (i.e. never compares its own precedence against any of the operators (even though it could)) and just goes to sit on top of the stack.

Thanks for your great example, with an assignment and other tricky bits! It's really helped me.

For the good of humanity, such lectures should records and presents.

Well thank you :D Definitely saved me from failing an exam completely

Finally an understandable explanation of this. Thanks so much.

@kiran, your thinking is correct, because they are the same precedence, need to remove from stack (doesn't really matter with + on + or - on -) but is for + on - or - on +
