The smallest single digit is 1 and the smallest natural number is 0.

minus 4 degrees Celsius is denoted as 4; minus 4 degrees Celsius is counted as 4. "4" is read as four. "4" is read as minus four. +4 can also be written as 4.

Numbers like , 8844 are all positive. Numbers like 4, 11, 7, 155 are all negative.

0 is neither positive nor negative. Positive numbers are greater than 0 and negative numbers are less than 0.

Typically, above sea level is expressed as a positive number, and below sea level as a negative number.

Typically, profits are expressed as positive numbers and losses are expressed as negative numbers.

Normally, the number of people who get on the bus is expressed as a positive number, and the number of people who get off the bus is expressed as a negative number.

Typically, income is expressed as a positive number and expenses are expressed as a negative number.

Typically, an upside is represented by a positive number and a falling number is represented by a negative number.

Grade 1-6 Mathematics Knowledge Points:

1. Addition commutative law: the position of two numbers is added and the sum is unchanged.

2. Addition associative law: add three numbers, first add the first two numbers, or add the last two numbers first, and then add with the third number, and the sum is unchanged.

3. Multiplicative commutative law: when two numbers are multiplied, the position and product of the exchange factor remain unchanged.

4. Multiplication and associative law: multiply three numbers, multiply the first two numbers, or multiply the last two numbers first, and then multiply with the third number, and their product remains unchanged.

5. Multiplicative distributive law: multiply two numbers by the same number, you can multiply the two additive numbers with this number respectively, and then add the two products, and the result remains the same. For example: (2+4) 5=2 5+4 5

6. The nature of division: In division, the dividend and the divisor expand (or shrink) the same multiple at the same time, and the quotient remains unchanged. o divided by any number that is not o gives o.

Simple multiplication: multiplication of the multiplier, the multiplier at the end of the o, you can first multiply the front of the o, zero does not participate in the operation, a few zeros are falling, added at the end of the product.

7. What is an equation? The equation where the value to the left of the equal sign is equal to the value to the right of the equal sign is called an equation.

The basic property of an equation: both sides of the equation are multiplied (or divided) by an identical number at the same time, and the equation still holds.

8. What is an equation? A: An equation with unknowns is called an equation.

9. What is a one-dimensional equation? Answer: An equation that contains an unknown number and the number of unknowns is one-time is called a one-dimensional equation.

Learn examples and calculations of unary equations. That is, the equation of the substitute is exemplified and calculated.

10. Fractions: Put the unit"1"The number of equal portions or fractions that represent such a portion or fraction is called a fraction.

11. The law of addition and subtraction of fractions: the fractions with the same denominator are added and subtracted, only the numerator is added and subtracted, and the denominator remains unchanged. Fractions with different denominators are added and subtracted, first through the fractions, and then added or subtracted.

12. Comparison of fraction size: Compared with the fraction of the same denominator, the numerator is large and the numerator is small. Scores with different denominators are compared, first through the scores and then compared; If the numerator is the same, the larger denominator is smaller.

13. Multiply the fraction by the integer, use the numerator of the fraction and the product of the integer multiplied as the numerator, and the denominator remains unchanged.

14. Multiply fractions by fractions, use the product of numerators multiplied as the numerator, and the product of the denominator multiplied as the denominator.

15. The fraction divided by an integer (except 0) is equal to the fraction multiplied by the reciprocal of this integer.

16. True fraction: The fraction whose numerator is smaller than the denominator is called the true fraction.

17. False fraction: A fraction whose numerator is larger than the denominator or whose numerator and denominator are equal is called a false fraction. False score greater than or equal to 1.

18. With fractions: Writing false fractions in the form of integers and true fractions is called with fractions.

19. The basic properties of fractions: the numerator and denominator of fractions are multiplied or divided by the same number at the same time (except 0), and the size of the fraction remains unchanged.

20. A number divided by a fraction is equal to the number multiplied by the reciprocal of the fraction.

21. The number A divided by the number B (except 0) is equal to the reciprocal of the number A multiplied by the number B.

Grades 1-6 have the following math knowledge points:1. Weight unit conversion: 1 ton 1000 kg; 1 kg 1000 g; 1 kg 1 kg.

2. Price and quantity: unit price, quantity, total price; Total price, unit price, quantity; Total price, quantity, unit price.

3. Encounter problems: the speed of the encounter distance and the time of the encounter; Encounter time, encounter distance, speed and; Speed and distance traveled to meet time.

5. False fraction: The fraction whose numerator is larger than the denominator or whose numerator and denominator are equal are called false fractions. False score greater than or equal to 1.
