MathPad is a general purpose graphing scientific calculator for the Macintosh. It uses text worksheets rather than simulating buttons on a hand held calculator. This live scratchpad interface allows you to see and edit your entire calculation. Formulas can be entered directly and different values can be plugged in for easy "what if" calculating.
In addition to being a handy little calculator, MathPad can also take on larger problems. Simple plotting allows quick visualization of results. General purpose arrays allow calculations involving vectors, complex numbers, matrix algebra etc. 2D arrays can be displayed as grayscale or color images. Several examples are included showing such things as equation solving, curve fitting, vector calculations and numerical solution of differential equations.
