you can only input positive whole numbers and <,>,/,-,=,+,*,^. :( I don't know how to make it better. :( (<,>,= greater than, less than, equal to [not very useful], *multiplication, /=division,^= power to ) if you divide, it will show a rounded number (even if the number is whole) If you choose a too big number (eg 1000000000000000^1000000000) it might glitch. #test #calculator
