Mathematical quantitative relations commonly used in primary schools;
1, number of copies × number of copies = total. Total copies/copies = copies. Total copies/copies = copies.
2, 1 multiple × multiple = multiple. Several multiples ÷ 1 multiple = multiple. Multiply/Multiply = 1 Multiply.
3. Speed × time = distance. Distance/speed = time. Distance/time = speed.
4. Unit price × quantity = total price. Total price/unit price = quantity. Total price ÷ quantity = unit price.
5. Work efficiency × working hours = total workload. Total amount of work ÷ work efficiency = working hours. Total amount of work ÷ working time = working efficiency.
6. Appendix+Appendix = sum. And-one addend = another addend.
7. Minus-Minus = difference. Negative difference = negative. Difference+subtraction = subtraction.
8. Factor × factor = product. Product-one factor = another factor.
9. Divider = quotient. Dividend quotient = divisor. Quotient × frequency divider = frequency divider.
10, division with remainder: dividend = quotient × divisor+remainder.
Introduction to quantitative relations:
1, and the quantitative relationship is an optical system between numbers, numbers and unknowns, and unknowns and unknowns. Quantitative relations are widely used in solving mathematical problems. When a number is divided by two numbers in succession, the last two numbers can be multiplied first, and then the number can be divided by their products, and the result is unchanged, which embodies the operation of quantitative relationship.
2. The quantitative relationship is an examination item in the civil service examination administrative professional ability test. Common problems are: numerical reasoning, mathematical operation, etc.
3. Quantitative relationship is a kind of question in civil service examination. This paper mainly examines the ability of candidates to quickly understand and solve arithmetic problems. The knowledge involved and the materials used are generally not beyond the scope of high school.
In the highly developed modern information society, there will be a lot of information that managers need to accept and process quickly, scientifically and accurately, and many of these information are represented by numbers or related to numbers. Therefore, as civil servants, only by mastering the ability of fast mathematical operation can they be competent for modern information management.
