A fraction less than 0 is a negative fraction, or a negative finite decimal or a negative infinite cyclic decimal that can be converted into a fraction. For the addition and subtraction of negative fractions, the sum and difference signs are determined first, and then converted into the addition and subtraction of positive fractions. Subtracting a number is equal to adding the opposite of that number.
Two numbers that are opposite to each other add up to zero.
Fractions less than 0 are negative fractions, and the operation rules of negative fraction addition and subtraction are exactly the same as those of positive and negative integer addition and subtraction, that is: add two numbers with the same sign, take the same symbol, and add the absolute values. Add the two numbers with different signs, take the sign of the larger additive, and subtract the smaller absolute value from the larger absolute value.
A Study of Fractions in Ancient China:In the "Zuo Chuan" of the Spring and Autumn Period of China (770 BC and 476 BC), the size of the capital of the princes was stipulated: the largest should not exceed one-third of the capital of the Zhou Wen Kingdom, the medium should not exceed one-fifth, and the small one should not exceed one-ninth.
The calendar of the time of Qin Shi Huang stated that the number of days in a year was three hundred and sixty-five and one quarter. This illustrates:
Scores appeared very early in our country and are used in social production and life.

A fraction smaller than zero is a negative score.
-
A fraction less than zero is called a negative fraction, and when two integers are positive and negative, the result of division is a negative fraction. The negative sign can be written on the numerator, or on the denominator, or at the fraction line. The fractional value of the numerator that is pure zero is zero.
In the divisor method, since the divisor cannot be zero, the denominator of the fraction cannot be zero.

Hello, it is a pleasure to serve you and give you the following answer: the negative score is multiplied by the negative score, and the result is a positive score. Causes of the problem:
1.Negative fractions are not understood well enough to treat negative fractions as a negative number, but as a positive one. 2.
The concept of negative multiplication is not clear enough to treat negative multiplication as the multiplication of two negative numbers, but as the multiplication of two positive numbers. Workaround and practice steps:1
First, think of a negative score as a negative number, not a positive one. 2.Second, think of negative multiplication as the multiplication of two negative numbers, not the multiplication of two positive numbers.
3.Finally, keep in mind that a negative number is multiplied by a negative number, and the result is a positive number. Teaching:
1.First of all, it is important for students to understand the concept of negative fractions, so that they understand that a negative fraction is a good negative number, not a positive fraction. 2.
Secondly, students should understand the concept of negative multiplication and understand that negative multiplication is the multiplication of two negative numbers, not the multiplication of two positive numbers. 3.Finally, students are asked to remember that the negative number is multiplied by the negative number of the friend touch, and the result is a positive number.
Personal Tips:1Think of a negative score as a negative number, not a positive one.
2.Think of negative multiplication as the multiplication of two negative numbers, not the multiplication of two positive numbers. 3.
Keep in mind that a negative number is multiplied by a negative number, and the result is a positive number. Related knowledge: Negative numbers multiplied by negative numbers, the result is a positive number, this is because a negative number multiplied by a negative number, in fact, two negative numbers are multiplied, and a negative number is multiplied by a negative number, and the result is a positive number.

Negative numbers do not change, just invert the numerator and denominator below. For example, the reciprocal of minus two out of seven is minus seven.
The stupid reciprocal of finding a fraction is actually to swap the numerator of the fraction and the denominator of the fraction; If it's to find a score.
, you have to turn the band score into a false score first.
Then according to the method of finding the reciprocal of the fraction, the numerator and the denominator are reversed, and the reciprocal with the fraction is found.
Number theory reciprocalIn number theory, there is also the concept of the reciprocal of number theory, if the product of two numbers a and b, their product is about modulo m and more than 1, then we call each other the reciprocal of number theory with respect to modulo m. For example, 2*3=1 (mod5).
So 3 is 2, the number theory reciprocal about 5, the number theory reciprocal in China's remainder theorem.
is very important. And the liquid bureau accompanies the tossing and turning division.
A method for calculating the reciprocal of number theory is provided.
-
The reciprocal of a negative score is a negative or negative score, and it can never be a positive number.
-
The reciprocal of a negative fraction is still a negative fraction or a negative integer, and this situation is still negative and will not change.
-
The absolute value of the reciprocal of a negative number is the same as that of an integer, except that the reciprocal of a negative number is still negative.

Definition: A fraction represents a part of a whole, or more generally, any part of an equal number. A fraction less than 0 is a negative fraction, and the operation rules of the negative fraction addition and subtraction method are exactly the same as the operation rules of the positive and negative integer addition and subtraction method.

Yes, fractions include cyclic and non-cyclic decimals, and there is no positive or negative distinction. Here's why:
True fraction 1, definition: The fraction whose numerator is smaller than the denominator is called the true fraction. The true score is less than one.
Such as: 1 2, 3 5, 8 9 and so on. True fractions are generally discussed in the range of positive numbers.
A fraction with a value less than 1, i.e. a fraction whose numerator is less than the denominator (both are positive integers) is called a true fraction, but a fraction value equal to 1 does not count (that is a false fraction).
2. Miscellaneous. There is also sometimes a term for a "negative true score", which refers to a negative score with an absolute value of less than 1. There is no maximum true score. Note:
When the numerator is 0, it is not a true fraction; For example: 0 6, although 0 is less than 6, 0 6 is not a true fraction. The reason is that "the unit "1" is divided into several equal parts, and the number of such parts or parts is called a fraction".
Example of true fraction: 2 5 (two-fifths), the numerator must be less than the denominator in order to be called a true fraction.
A negative number is a real number less than 0, and a negative number is the opposite of a positive absolute number. Any positive number preceded by a negative sign equals a negative number.
The unit "1" is divided into several parts, and the number of such parts or parts is called a fraction. Whereas, negative numbers refer to real numbers that are less than 0. Fractions are also real numbers, that is, both are just a subset of real numbers, and they will intersect, but they are not containing.
When there is a large disparity between the strength of the two teams in the game, the lottery issuer will balance the strength of both sides by handicap according to the actual situation. The strong team will be the handicap side, and the weak team will be the handicap side.

In the Han Dynasty, the commercial activities of the Grange were very active, and there were two parallel and closely related markets of the Grange's internal market and the external market. The transactions in the Grange's internal market are mainly for the purpose of satisfying the needs of daily life within the Grange, while transactions in the Grange's external market are mainly for the purpose of obtaining money and appreciation. The two markets formed by the active commercial activities of the Han Dynasty Grange were the result of the way the Han Dynasty Grange was operated, especially the Han Dynasty's policy of valuing people over land.
