There is a famous algorithm for solving this exact problem. Your solution only handles the most trivial case of only 2 numbers with one operator. Which is the practical difference between a server and a web server? I'm making a calculator app to challenge myself and I need a hand in planning my logic. how to translate statements from English into frst-order logic. The only limitation for this calculator is that you have only three atomic propositions to choose from: p,q and r. Thing is, the equation is in a single string and I need to somehow figure out the numbers on the left and right hand side of an operator which I am evaluating (there is an order of operations) . To learn more, see our tips on writing great answers. Reverse Polish Notation? What is the logic behind calculating diagonals on a chessboard? D ≡C / ∴--> 'Therefore' (conclusion) See the las… Key . rev 2020.11.24.38066, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, Yeah, I've seen this one before. do they affect the order of operation - and include in the regex, Edit: And just for fun (and because of the down vote), I've create a simple example here (plus, minus, multiply and divide operators only, no spaces between numbers and operators), Edit 2: Updated fiddle (allows multiple operators in expression and decimal numbers), Edit 3: Updated fiddle (include power operator - 2^3=8), Edit 4: Updated fiddle (takes into account parentheses, white space, divide by zero), First a treelike structure comes to mind. It's a good idea, but unfortunately it would be rather hard to implement this considering that everything is passed through as one string. your coworkers to find and share information. The simplification of Boolean Equations can use different methods: besides the classical development via associativity, commutativity, distributivity, etc., Truth tables or Venn diagrams provide a good overview of the expressions..

Example: Original expression (LaTeX) $$ \overline{a \land b \land (c \lor \bar{d})} \lor \bar{b} $$ dCode allows several syntaxes: Is it a usual practice from pianists to remove the hand that does not play during a certain time, far from the keyboard? How could I align the statements under a same theorem. Making statements based on opinion; back them up with references or personal experience. The Shunting-yard algo can be supplemented and enhanced to handle precedence and associativity. Should live sessions be recorded for students when teaching a math course online? We will give two facts: john is a father of pete and pete is a father of mark.We will ask whether from these two facts we can derive that john is a father of pete: obviously we can.. This does provide some help on actually parsing the tokens from the string, but the process of evaluating order of operations and dealing with brackets is not trivial. eg - I'm trying to evaluate something like 5+5^-2-3. The simplification of Boolean Equations can use different methods: besides the classical development via associativity, commutativity, distributivity, etc., Truth tables or Venn diagrams provide a good overview of the expressions.. A first prototype of a ProB Logic Calculator is now available online.With it you can evaluate arbitrary expressions and predicates (using B Syntax).It is a great way to learn about B, predicate logic and set theory or even just to solve arithmetic constraints and puzzles. Variable length arithmetic calculator WITHOUT using strings? The Propositional Logic Calculator finds all the models of a given propositional formula. The shunting yard algorithm is for converting from infix (i.e. Translating English to Propositional Logic Phil 57 section 3 San Jose State University Fall 2010 Slideshare uses cookies to improve functionality and performance, and to … Chapter 7 focuses on simply translating regular English statements into a new symbolic language. But if you want it very simple, depending on the language i'd create an array, [[5,number],[+,operator1],[5,number],[^,operator3],[-2,number],[-,operator1],[3,number]]. Maybe you should have your answer just cover the tokenizing aspect of the solution, but don't give an incomplete, ultimately wrong solution to the larger problem at hand. Translating English to Propositional Logic Phil 57 section 3 San Jose State University Fall 2010 Slideshare uses cookies to improve functionality and performance, and to … Usually this is due to less than perfect English language skills. Stack Overflow for Teams is a private, secure spot for you and
(factorial of 26), which is about . For many students translating is one of the hardest parts of learning how to do symbolic logic. Now we will be introducing new symbols so that we can simplify statements and arguments.
