why tell someone to enter "Enter Number or Equation to solve problem." when trying to input a number or equation it says incorrect, just say "please enter 'a+b'"
Because it makes you think.
'Please write their sum' can be misunderstood, it should probably say 'Write the equation.'
it will become harder
how do you know.
it does become much harder
im on arrays now
is there a way to reset your progress?
