However, a sheet of common copy paper that has a basis weight of 20 pounds (9.1 kg) does not have the same mass as the same size sheet of coarse paper (newsprint). In the former case, the standard ream is 500 sheets of 17-by-22-inch (432 by 559 mm) paper, and in the latter, 500 sheets of 24-by-36-inch (610 by 914 mm) paper.

Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
In computational complexity theory, the language TQBF is a formal language consisting of the true quantified Boolean formulas.A (fully) quantified Boolean formula is a formula in quantified propositional logic (also known as Second-order propositional logic) where every variable is quantified (or bound), using either existential or universal quantifiers, at the beginning of the sentence.
The Andreotti–Norguet formula was first published in the research announcement (Andreotti & Norguet 1964, p. 780): [7] however, its full proof was only published later in the paper (Andreotti & Norguet 1966, pp. 207–208). [8] Another, different proof of the formula was given by Martinelli (1975). [9]

The next step is to define the atomic formulas. If t 1 and t 2 are terms then t 1 =t 2 is an atomic formula; If R is an n-ary predicate symbol, and t 1,...,t n are terms, then R(t 1,...,t n) is an atomic formula; Finally, the set of formulas is defined to be the smallest set containing the set of atomic formulas such that the following holds:
