Multiple and multiple differences:
In the first period, we learned the concept of "times", and in the second period, we learned the concept of "times". So, are the words "multiple" and "multiple" the same thing? What's the difference between these two words?
"Times" refers to the quantitative relationship, which is based on the concept of multiplication and division. For example, boys 10, girls 30. Because "10×3=30" or "30÷ 10=3", we say that the number of girls (30) is three times that of boys (10). Bo Ning said that "times" is actually the quotient of two numbers (this quotient can be an integer, a decimal, a fraction and other expressions).
"Multiplication" refers to the relationship between numbers, which is based on the concept of divisibility. For example, 30 is divisible by 6, and 30 is a multiple of 6. It can be seen that "multiplicity" cannot exist independently (with specific directivity), and the form of logarithm has special requirements (it must be an integer).
