Sider’s examples: (P ∧ Q) → R and P ∧ (Q → R) become → ∧PQR and ∧P → QR.If you actually look at a text in this tradition, you’ll find something slightly different. “C” stands for “consequence”, i.e., implication (→) and “N” for negation (∼).So,consider the following from Tarski and Łukasiewicz’s Investigations into the Sentential Calculus. The claim there is that there are three axioms:    ‘CCpqCCqrCpr’    ‘CCNppp’    ‘CpCNpq’ Synonyms en prefix notation Translations notation for arithmetic formulae Bulgarian: bg полски запис m Chinese: Mandarin: cmn 波蘭表示法 Bōlán biǎoshìfǎ Czech: cs polská notace f Finnish: fi puolalainen notaatio French: fr notation polonaise f German: de Polnische Notation f Greek: el πολωνικός συμβολισμός m Japanese: ja ポーランド記法 Pōrando-kihō Polish: pl notacja polska f, pl zapis przedrostkowy m, pl notacja Łukasiewicza f, pl notacja prefiksowa f, pl symbolika beznawiasowa f Portuguese: pt notação polonesa Romanian: ro notație poloneză f Russian: ru по́льская нота́ция f Spanish: es notación polaca f See also en infix notation en postfix notation en reverse Polish notation
