What’s on the Truth Tables poster
A 4-row table: p, q · p ∧ q · p ∨ q · p → q.
The whole of propositional logic, in four rows.
- T, T — T — T — T
- T, F — F — T — F
- F, T — F — T — T
- F, F — F — F — T
p → q is false only when p is true and q is false. A false premise makes the implication true, which is where intuition gives out.
Questions about the Truth Tables poster
- What’s on the Truth Tables poster?
- A 4-row table: p, q · p ∧ q · p ∨ q · p → q. The whole of propositional logic, in four rows. T, T — T — T — T; T, F — F — T — F; F, T — F — T — T; F, F — F — F — T. p → q is false only when p is true and q is false. A false premise makes the implication true, which is where intuition gives out.
- Who is the Truth Tables poster for?
- Truth Tables belongs to the Mathematics section rather than to a school year, because math is not something one grade owns. Anyone learning discrete mathematics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Truth Tables poster?
- For checking an equivalence, or settling an argument about what implication means. A wall chart earns its place by being glanceable from where the work is happening, so Truth Tables belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Truth Tables?
- The Binomial Theorem, Counting Principles and Euler & Hamiltonian Paths sit alongside Truth Tables in the Mathematics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.The Binomial TheoremCounting PrinciplesEuler & Hamiltonian Paths
- Is the Truth Tables poster free to download and print?
- Yes. Truth Tables downloads as a free PDF with no account, no email and no watermark, like everything else in the Mathematics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Truth Tables poster print at?
- Truth Tables is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Truth Tables loses nothing.Printing guide
