According to mathematical rules, the process of replacing or transforming a quantity or number to get the result of expression. It is the main content of mathematics research, and mathematics is the subject of studying quantity and its operation, graph and its transformation. The most basic operation of numbers is four operations.
Mathematical operation rule table, a technical term, is a mathematical tool, and its pinyin is sh ù xué y ù n su à n f m ù zé bi m ù o. For example, the operation of combining two numbers into one number introduced in it is called addition, each added number is called addend, and the added number is called sum.
Content of mathematical operation
Integer addition, the operation of combining two numbers into one number is called addition. In Djaafari, the added number is called addend, the added number is called addend, the addend is part number, the addend is sum, the addend is equal and one addend is equal and the other is addend.
Integer subtraction, knowing the sum of two addends, is called subtraction. In subtraction, known sum is called minuend, known addend is called subtraction, unknown addend is called difference, minuend is sum, subtraction and difference are partial numbers respectively, and addition and subtraction are reciprocal operations.
Integer multiplication is a simple operation to find the sum of several identical addends, which is called multiplication. In multiplication, the same addend and the number of the same addend are called factors, and the sum of the same addend is called product. In multiplication, 0 is multiplied by any number to get 0. 1, and any number is multiplied by any number.
