What are the positive and negative numbers in life, examples of positive and negative numbers in lif

1) Thermometer.

2) Floors. 3) As of January 2011, the People's Bank of China lowered interest rates. As of now, the central bank's interest rate has risen again.

Haha, God help me. Isn't this a pair of positive and negative numbers? A downward adjustment can be written as —and an upward movement can be written as a +. It's a great way to find positive and negative numbers.

4) Our family's monthly income is 3,000 yuan, which is expressed as +3,000; Expenditure of 1,500 yuan; It is expressed as -1500.

5) If you deposit 1000 yuan in the bank, it is +1000;Take out 300 yuan, that is, -3006) The factory earns 500,000 yuan in a month, which is +500,000, and the loss of 200,000 yuan is -200,000.

7) The water level of the barrage dam rises by two meters is +2, and the water level drops by meters, which can be expressed by -.

8) ** Up and down.

9) GDP (Actually, I still don't understand what it means......10) Positive and negative scores.

** Ah GDP Ah Bank Rate Ah Fraction.

Match scores, **, weather.

Each one in life can be an opposing positive or negative number.

The positive and negative numbers in life are:

1. Temperature: When measuring the temperature, 0 degrees is used as the demarcation point, and the temperature lower than 0 degrees is called the sub-zero temperature, and when it is lower than 0 degrees, add a negative sign before the value, such as: 3 is represented as minus 3 degrees or minus 3 degrees.

The temperature higher than 0 degrees is called the temperature above zero, and a positive sign is added before the value, such as: 5, which means 5 or 5 above zero.

2. Altitude: The height of the sea level relative to the sea level is expressed as 0. It is 8,848 meters above sea level and is expressed as a positive number and is called 8,848 meters above sea level. 155 meters below sea level, expressed as a negative number, is called 155 meters above sea level.

3. Quantitative statistics: For example, a total of 25 new students transferred from the fourth grade of the school should be counted as 25, and 18 students transferred from the fifth grade should be counted as (18). In the process of doing the question, "5 correct" is recorded as "5", and "5 incorrect" is recorded as (5).

4. Direction distance: For example, if there is a provision that walking 500 meters to the east is recorded as 500 meters, then walking 200 meters to the west is recorded as 200 meters.

5. Profit, production increase, production reduction, expenditure Income: income is positive, expenditure is negative; The surplus is positive and the deficit is negative; The increase in production is positive, and the decrease in production is negative. These are the first of its kind in the world for Chinese to use negative numbers.

For example: income and expenditure are negative, this month's income is 100,000 yuan, this month's expenses are 110,000 yuan, 10-11 = -10,000 yuan, so it is a loss.

Temperature - how many degrees below zero.

Floors - how many floors underground.

Time - a few minutes or less.

Distance--How many meters to **temperature (temperature, how much is below zero), altitude (Turpan is just below sea level), money (owing money to others is negative), and so on.

For example, when taking the elevator, the underground floors are the negative number, and on the contrary, the upper floors are the positive number.

Playing games is also divided into positive and negative numbers.

Examples of negative numbers in life are:

1. The temperature indicates the temperature below zero.

2. For the underground part of the building, the basement floor is represented by a negative floor.

3. Altitude below sea level is expressed as a negative number.

4. The lowest temperature on the Earth's surface in Antarctica, is.

5. The temperature of water above 0° is positive, then the temperature of ice below 0° is negative.

Negative numbers are mathematical terms, numbers smaller than 0 are called negative numbers, negative numbers and positive numbers represent quantities with opposite meanings, any positive number preceded by a negative sign becomes a negative number, and a negative number is the opposite of its absolute value.
