just type in your equation using they keyboard
u/joeytwiddle

For example, click on the canvas and type: 40+X*X*X/999
u/joeytwiddle

Very cool idea. I changed your regexp to /[\--9XYS()+*]$/ then I could do 30+30*S(X/9)

Extremely small tarot reader! You actually can use this #witchcraft #tool as a divination method. Here's how to use: ask a question by writing it after the // at the end (include the ? symbol). Then take a look at the result in the error section. Remember: p = page, k = knight, Q = QUEEN, K = KING, Y = cups, | = wands, ⚔ = swords, ⍟ = pentacles. Examples Q of ⍟ = Queen of pentacles, 5 of ⚔ = Five of swords, K of Y = King of cups. Have fun

You can use n(h) to play notes, h is half step offstep from middle C. Tetris Music = f=n([4,z,-1,0,2,z,0,-1,-3,z,-3,0,4,z,2,0,-1,z,-1,0,2,z,4,z,0,z,-3,z,-3,-3,-3,z][i/8%32|0])
