Reverse the order of the selected item on the stack and all items higher (newer). So the selected item swaps places with the x register, next oldest item swaps with the y register, etc.

Apply a function to all integers in a specified range, and push each result to the stack. So, it basically works exactly like \(\sum \left ( f, v, y, x \right )\), except that it pushes each calculation rather than adding them and returning the sum.

Use the various rationalize snippets already posted to try to turn the results of MathZero into a perfect number. This can replace the standard MathZero in the toolbar if you so choose. Unfortunately doesn't play nice with the other solver functions the way the stock MathZero does.

Compute \(\text{solve}\left ( f_{1}= f_{2}, v, x \right )\) where \(f_{1}\) is in the t register, \(f_{2}\) is in the z register, \(v\) (the variable to solve for) is in the y register, and the initial guess for an answer is in the x register.

Replace the standard + button with a + button that will treat the selected line in your stack as the top of the stack. So, selected line is replaced with sum of selected line and the line above it. Works exactly like normal + if nothing is selected. It should be pretty obvious from this snippet how to replicate for −, ×, and ÷

Add \(\text{sech}\) and \(\text{sech}^{-1}\) as long-press on existing \(\cosh\) and \(\cosh^{-1}\) buttons. It should be pretty obvious from this snippet how to replicate for \(\text{csch}\) and \(\text{coth}\).
