I have just stumbled onto your web pages, but I have not yet perused the items.
What I can't find is how to write some arithmetic in a form which is professional which is not the way I do it.
For example the number 20.612 x 10,000 cubed x 10 cube root squared and /40 and square root 4 times /Pi
x 1,000 = 1,284.260311.
Or 186,282.432 cubed x 10 and cube root x 1.5 x 1.5 and /700 = 1,290
Or 1.3900000e+13 and /4 and square root twice x 3 and square root twice = 8.00000004
I will pay a fee for your help because the examples are important in my research.
Sincerely,
