xPapertape Calculator

Papertape Calculator keeps a record of every entry made by the user. It displays, on a "papertape", all of the entries made in a calculation and saves the user time since a review of the papertape is all that is needed to check one's work. Re-entry of the data is not required.

It also simplifies several otherwise complex calculations such as mean, median, mode, variance, standard deviation, root mean square, linear least squares regression and multiple regression.

This calculator updates the relevant data as each data point entry is made. This shows the user how each data point contributes to the final result.

The calculator also offers the user a variety of pre-programmed calculations for lines, planes, quadratic and cubic equations, bessel functions, loan and amortization calculations and annuities.
