## Symbols Description
Learn logic with Symbols, the app that teaches natural deduction and the rules of inference in an intuitive, accessible way. Our unique Studycards feature visual pictographs and interactive, step-by-step exercises that allow you to grasp each rule easily and quickly. Then, challenge yourself with activities specifically designed to practice those rules, building your skills progressively, and cementing them in your memory with every level completed.

Why Symbols?

Comprehensive Studycards: Learn essential rules like Modus Ponens, Modus Tollens, Disjunctive Syllogism, and many more through clear explanations and examples. Perfect for students and anyone looking to understand formal logic.

Engaging Activities for Skill Mastery:

Validity: Sharpen your critical thinking by evaluating pre-solved arguments. This unique activity provides the benefits of repetition without the tedium, helping you apply, recognize, and grow familiar with the rules of inference.  

Justification: Challenge your understanding with puzzle-like scenarios where you deduce missing argument steps. This deepens your comprehension and refines your application of logical rules within complex arguments.

Inference: By this stage, the training wheels are off, and the student has to draw on everything they've learned so far. Their task is to mentally build a valid argument from what’s provided—or to recognize that no valid argument can be formed. What would normally be worked out slowly on paper is now done at the speed of thought.

Translation: Translation helps students practice turning statements with indicator words and phrases into logical form. These indicator words, commonly found in logic books and courses, give students a sense of how to translate everyday language into formal logic. Translation breaks this process into levels, allowing students to track their progress and earn new scores as they build proficiency.

Download Symbols for free and begin your journey into formal logic. Your free access includes the first level of every activity and the Modus Ponens study card, a must-have for getting started. For more advanced content and features, simply use our in-app purchases to continue building your logic skills.

Start your journey of mastering the rules of inference now!

## Symbols Reviews in United States

### ***** "Symbolic Logic Lovers: Great App for Downtime (No More Endless Phone Scrolling!)"
I am someone who took a few formal logic courses in college and fell in love with symbolic logic. I have long been looking for some kind of simple phone application that would allow me to practice/review logic skills for fun during the times where I would both like to avoid using my computer for hobbies such as taking free courses but would also prefer to avoid simply surfing the internet on my phone. 

I had envisioned an application for symbolic logic that would be similar to the multiplication and division sheets I loved completing back in elementary school—simple, straightforward, effective, and fun. This app fits the bill perfectly. I want to thank the developer(s) for creating my dream application. No more mindlessly scrolling on my phone while waiting for appointments or relaxing at the end of the day—now I have symbolic logic to fill that void!

### ****- "Certain problems are wrong, other than that it’s a cool app"
In one game, you have to translate words into symbolic logic. One example is “If X, then Y”, which would be represented as: X ⇒ Y. 
One problem actually is incorrect, from what i’ve found. “Only if” is represented as a conditional with the antecedent and the consequent flipped. “X only if Y” is not X ⇒ Y, it’s Y ⇒ X. That’s why a biconditional is spoken as if and only if, it includes both the “if” and “only if”.

Other than that, it’s a cool app.

### ****- "Great Learning Tool, learning progress should be shared across activities"
This app teaches you how to do symbolic logic. There are several activities, and several levels. The first level is extremely simple. To proceed to the next level, you must complete the current level several times. My complaint is that arduous progress in one activity is not shared to the other activities that use the same logic. I don’t want to train modus ponens separately for each game.
