I tried doing this a few times. I failed Can someone explain the logic behind doing this? like how its all looped? i only need +-x/ like windows calc it displays the number when buttons are pressed and inputs each value one at a time |

Maybe share one of your attempts, and explain in what way it failed? |

It failed because I dont know what im doing. so basically ill explain what my code does theres GUI buttons, 0-9, + - x / = and a little screen for showing numbers When you click a number button, it adds a digit to a string variable which is displayed. when you press an operator the variable locks as number 1 as a real number using realstr, and the operator is set too. then i got lost because i dont know what to do afterwards |

Help, I also need it to keep repeatedly allowing more numbers. so you can do 1+1+1 for example... that is getting me confused the most Edit: Would it be better to avoid GUI and use coordinate buttons? |

Maybe avoid GUI completely for now, just build the underlying calculator. Trying to work on that _and_ GUI at the same time is just extra confusing. It sounds like you are almost there. You've locked in your first number and an operator. Now you need to lock in your second number (should be very similar to locking in first number) and execute the operation. I think the trick to 1+1+1 is that it's really 1+1+... and it doesn't at all matter what follows. There are no parenthesis and no order of operations. You'll do that first addition the same way as if there was nothing else following it. |

I'm afraid I don't quite get you. What do you mean it doesn't matter what follows? I think I'm more confused on how to lock a value onto the first number and then switch to locking the next one. like math should also display after you press for example: 9, 9, +, 8, + this will output 107 just like on windows calc |
