the point of this program is to input a math formula and get the answer... it only works with */+- at the time but i'm working on brackets. |

ya, thats what I said earlier in my post... first you have to search your operations for any *s and /s... And do them first. Then resort your array and do left to right the way you have it now once only +- are left. let me give you an example 1 + 2 * 3 - 1 the result should be 6, though your program will output 8 now if you search for *s first... 1 + (6) - 1 after calculating 2*3 you store its value in the place of 2. Then you move the rest of your array down one spot to get rid of non existing *3 (since its already calculated). |

that one doesn't filter the bedmas though ie. 1+2*3 = 7 the program will say 9 |

that is a good caclulater but my projects is a totally different thing when i finish it will be able to give you the answer to x = 2x + 3 I dont think that calc can do that.... |

well for your program you could have a for loop running all possibilities from -1000 to 1000 and an if statement checking to see if it's correct. eventually you'll find the answer. |

well like real-life calculators there can be a character limit. |

that's true but first of all not all caclulators solve equations and the ones that do dont do it by guessing numbers... |
