English
Let a and b be integers with a interpreted in the additive sense and b as an exponent; the relation between multiplication and exponentiation under the additive–multiplicative correspondence is given by the identity: ofAdd (a * b) = ofAdd a ^ b.
Русский
Пусть a и b — целые числа; в рамках аддитивно-мультипликативного соответствия имеет место равенство: ofAdd(a · b) = (ofAdd a)^b.
