Hi there,
I'm going to write a program about mathematics that could do mathematical operations. About this, I have my friends helping me write it. If it becomes a complete software in Math, i.e sketching functions, solving equations and many other thing in math, would it be valuable to buy? If I'm gonna sell it as an official software in the world, how much you think will it cost? and how many copies of it will be sold? I mean how many would pay money for it?
And of course I'm sure it will take much time to make; Maybe about 2 or 3 years.
I would be grateful if you answer my questions.
Thanks
