Interpretation of symbols in logic and math

Reading logic formulas

p → q

  • if p then q

  • given p, q

  • p implies q

  • q only if p

  • q is the necessary condition for p

  • p is a sufficient condition for q

if {it works} then {it'll revolve}

  • given that it works, it's revolving

  • it revolves only if it works hmm

p → ¬¬p

  • if p, then it is NOT the case that NOT p

p ⇔ q

  • p if and only if q

  • if p then q and if q then p

(p = T) → (¬p = F) ∧ (¬¬p = T) if p is TRUE, then NOT p is FALSE and NOT NOT p is TRUE

p = ¬¬p

  • if p is TRUE, then NOT NOT p is TRUE

  • if p is FALSE, then NOT NOT p is FALSE

p = ¬¬p ¬¬q = q p ∧ q

p → q

  • if p then q

    • if {it rains} then {the streets are wet}

  • given p, then q

    • given {that n ∈ ℕ and even} then {n >= 0 and n ×÷⁒±‗ 2 = 0}

  • p implies q

  • q only if p
