|
|
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.

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