Mathematics in Life Essay. 400 words.

Air is everywhere and smellless, but we can't do without it. The same is true for mathematics. The great mathematician Hua Luogeng said:

The universe is big, the particles are small, the rockets are fine, the chemical industry is ingenious, the earth is convenient, and the daily use is complicated, and mathematics is everywhere. "When we started to hit the ground, math was all around us. Full moon, 100 days, 100 years old, ......... year oldCount of increased age.

When I grew up, I began to receive a systematic education in mathematics, learning to count, add, subtract, multiply and divide operations.

When buying groceries, it is mathematics to give money and find money; When cutting paper, the size and area of the paper is mathematical; When eating, it is math to divide the food evenly among everyone. I remember the first time I went to the vegetable market to buy vegetables alone, while picking the vegetables that I and my parents loved to eat, I carefully calculated the accounts, and the last money was not wrong. And the first time I went to the supermarket, I was careful and exchanged a lot of food and daily necessities.

Using mathematics, some troubles can always be simplified and solved. When learning chess, how do you express chess? After you mark the line on the chessboard with numbers, you can use the simple chess games of "running two flat five" and "rook three flat four" to describe a game of chess very completely, and it is precisely because of the chess game that there is blind chess.

Mathematics is like a treasure buried in the ground, which needs to be excavated slowly, and to learn mathematics well, we must be rigorous and steadfast, and have the courage to try. When I encounter difficulties, I will dig out the hidden conditions from the problem, such as the time of year, month, day, and the sum of the inner angles of the triangle, and find solutions to the problem. When I learn to use it, I'm pleasantly surprised that I've mastered another skill that will be excited to discover the next puzzle and can't wait to solve it.

Mathematics exists everywhere all the time, and we use mathematics in our lives, which provides great convenience for our lives; Teachers link math and work to ensure that they can successfully complete their work; Scientists have combined mathematics and science to make great contributions to the improvement of our scientific and technological level.

Mathematics is like air, without taste, but it is an indispensable and important existence for us to learn, live, work and develop science and technology.

If Mr. Song pays 696 yuan of personal income tax, how much is this manuscript fee?

The first limit theorem in the history of probability theory belonged to Bernoulli, which later generations called the "law of large numbers". In probability theory, the law of convergence of the arithmetic mean of a sequence of random variables to the arithmetic mean of each mathematical expectation of random variables is discussed. The law of large numbers is divided into the law of weak large numbers and the law of strong numbers.

4. Common examples of large numbers in life:

The longest river in China is the Yangtze River with a length of 6,397 (six thousand three hundred and ninety-seven) kilometers, the largest lake in China is Qinghai Lake with a circumference of 360 (three hundred and sixty) kilometers and an area of 4,500 (four thousand five hundred) square kilometers, the fastest train in China is the Shanghai Maglev train with a speed of 430 (four hundred and thirty) kilometers per hour, the largest continent in the world is Asia with an area of 4,400 (four thousand four hundred) thousand square kilometers, and the largest country in the world by land area is Russia with an area of 17, 075,870 (1,775,870) km², the highest oak mountain in the world is Mount Everest, its height is 8,8848.8) meters, the longest river in the world is the Nile with a length of 6,671 (6,671) kilometers, and the deepest lake in the world is Lake Baikal with a depth of 1,741 (1,741) meters.

3) By calculation, the circumference of a circle with a diameter of 10cm is;

4) China's national economic growth in 1999.

Exact numbers: (1) 1998 and 1978 (year is the exact number).

2) 52 (52 is a prime number).

3) 10 (10cm is a precise distance).

4) 1999 (year is an exact number).

Approximate numbers: (1) 15 million and 12 (approximate numbers 15 million yuan, accurate to 10,000 digits, with four significant figures; The approximate number 12 is accurate to the single digit and has two significant figures).

2) and approximate numbers accurate to the percentile, with 3 significant figures; Approximate numbers are accurate to the decile place, with 3 significant figures).

3) (Because is an approximation of , and pi is indivisible, it is an approximation).

4) When it is not easy to obtain, or it is impossible to obtain an accurate number, only an approximate number can be obtained, such as the result of the census, which can only be an approximate number).

It's very theoretical.

Profit = 125-100 = 25 Profit margin = 25 100 * 100% = 25% Selling price = 125*

2) Greater than than.
