Order of Operations Calculator

Rewritten in JavaScript: Order of Operations Calculator

Does it work for you?

Any issues at all?

Re: Order of Operations Calculator

Hi;

Worked on all my test problems. The tree is a nice idea.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

hi MathsIsFun

I, too, like the tree.  Everything I tried worked.  Do you have a plan for dealing with things like:

tan(pi/4) = 0.9999999999999999

Scientific calculators have an option for switching to degrees.  Any chance of that ?

Thanks for the tests. I will look into a Deg/Rad switch.
