small project challenged to me by my job coach, first day was headaches second day was the plan third day was bad code fixing more bad code until i did it ( insert phil swift flex tape bad code meme here ) al in all, bout 3 days of work, handles parentheses, ( any combo you can imagine, parentheses in parentheses beside parentheses ) does not handle negatives as negatives are handles as subtraction. you can always just subtract by 0 in parentheses, or i could add a special character that would act to set a value negative im not even going to start to explain how this works like usual...
