For example:
The relationship between addition, subtraction, multiplication and division;
1, addend+addend = sum. And-one addend = another addend.
2. Minus-Minus = difference. Negative difference = negative. Difference+subtraction = subtraction.
3. Factor × factor = product. Product-one factor = another factor.
4. Divider = quotient. Dividend quotient = divisor. Quotient × frequency divider = frequency divider.
The corresponding explanations of addition, subtraction, multiplication and division of extended data are as follows:
1, addition is one of the four basic operations, which refers to the calculation of combining two or more numbers and quantities into one number and quantity. The symbol of addition is the plus sign "+". Connect items with a plus sign when adding.
2. subtraction is one of the four operations, and the operation of subtracting one number from another is called subtraction; Given the sum of two addends and one of them, the operation of finding the other addend is called subtraction. The symbol of subtraction is "-",which is pronounced as negative sign.
3. Multiplication is a shortcut to add up the same numbers. The result of its operation is called product, and "X" is the symbol of multiplication. From the philosophical point of view, multiplication is the result of qualitative change caused by additive quantity. The multiplication of integers (including negative numbers), rational numbers (fractions) and real numbers is a systematic summary of this basic definition.
The division of two numbers is also called the ratio of two numbers. If ab=c(b≠0), the operation of finding another factor A by multiplying the product C and the factor B is division, which is marked as c÷b and pronounced as C divided by B (or B divided by C). Among them, c is called dividend, b is called divisor, and the result of a operation is called quotient.
