DefinitionNumber theory – is a branch of mathematics that provides the study of integers and its properties. Engineering mathematics the operation of processes and their effect in algebra, calculus, and several different types of mathematical or analytical operations or by differential equations exactly with order theory. It further involves prime numbers and sometimes general properties of terms, numbers, terms, and sets – as it related to the argument of cryptography centuries ago, and property to be shown or not. Example: Fermat’s last theorem. the assertion that there are no three positive integers that will satisfy for every unequal integer extension of 2. explain what a partial derivative is. how can it relocate differ?
