Is there a way to change the default multiplication symbol in a polypad into the dot operator? Or at least to enter a dot operator into an individual expression?

Hi, I don't know where you want to use this symbol but in a textbox you can copy nearly any Symbol you want. I often use Unicode Symbols. You can find the needed Symbol via searching the web .

Hi Barbara -

That is not currently an option, but I'll add it to our list of user requested features. In the meantime, you can use parentheses to represent multiplication. Thanks for passing along the idea!
