A calculus is nothing more than a system of production rules for printing images. > Uninterpreted formal system. - The calculi differ in their use of the operators.
HH 270
Calculus/HH. Progress for the decision problem: for the problem solution one can accurately construct the calculi that are adequate. - There are calculi, which produce exactly those print images that are identical with print images of universal problem solution formulas. - The adequacy of the calculus only says : if the formula is universally valid, then there is a proof in the calculus.
