Another way to interpret all of those symbols would be to work with the numbers 0 and 1, interpreting the symbol 0 as the number 0, S as the function that maps 0 to 1 and 1 to 0, + as addition mod 2, * as multiplication mod 2, and (just for variety) E as the function with constant value 1. " Or, if I were in a slightly more bizarre mood, I could work in a universe consisting of Beethoven, Picasso, and Ernie Banks, interpreting the symbol 0 as Picasso, S as the identity function, < as equality, and each of the binary function symbols as the constant function with output Ernie Banks.

J> is (~ia) and v is free in a, or ' 3. is (a V P) and v is free in at least one of a or (3, or 4. 4> is (Vu) (<*) and v is not u and v is free in a. Thus, if we look at the formula \/v2~>{ivz){vi — S(v2) V l>3 = V2), - the variable vi is free whereas the variables V2 and V3 are not free. A slightly more complicated example is (V»iVt*(t;i + v2 = 0)) V vi = 5(0). , In this formula, vi is free whereas V2 is not free. Especially when a formula is presented informally, you must be careful about the scope of the quantifiers and the placement of parentheses.

In the inductive step of the proof, we prove the implication If the formula holds for k, then the formula holds for k •+1. We prove this implication by assuming the antecedent, that the theorem holds for a (fixed, but unknown) number k, and from that assumption proving the consequent, that the theorem holds for the next number, k + 1. Notice that this is not the same as assuming the theorem that we are trying to prove. The theorem is a universal statement—it claims that a certain formula holds for every natural number.
