Hello project owner , it seems like a very interesting project !! i would like to ask some questions about "Mathematical elements" , you a referring to geometrical elements? or mathematical symbols? or whatever we are inspiring into?
Thanks a lot , and good luck with all

I could imagine the use of mathematical tools (set square, protractor, slide rule) as well as symbols like infinity, square root, etc.

Think of the best children's' illustrators. Not manga or Disney.

I like the Wild Things by Maurice Sendak

Hello, how many characters do you expect to receive in this first stage? Would three examples be enough? Thank you

Yes, somehow incorporating math symbols and or tools into the character so that they are part of the body.
