Typing Math — Using the Keypad in Modmath 4.0

The Modmath virtual keypad gives you access to numbers, operators, and advanced math symbols. This article is a complete guide to every key and tab.

 

Opening the Keypad

With the keypad tool selected (Add Equation ), tap any cell on the canvas to open the keypad. The keypad will show and hide based on the tool you have selected.

 

Collapsed vs. Expanded

The keypad opens in collapsed mode — a compact keypad showing the number pad and Undo/Redo buttons.

Tap the open keypad button (box with an arrow to the left) on the left edge of the keypad to expand it. The keypad grows to show the other tabs ADV1, ADV2, and ADV3. 

Tap the close keypad button (arrow now pointing the other direction) to collapse.
