Zu Chongzhi. A.D. 429 500).
Zu Chongzhi (429-500) was a mathematician, astronomer, and physicist of the Southern and Northern Dynasties of China. Zu Chongzhi's grandfather's name was Zu Chang, and he was a prefect in the Song Dynasty who managed the buildings of the imperial court. Zu Chongzhi grew up in such a family, and he read a lot of books since he was a child, and everyone praised him as a learned young man.
He was particularly fond of mathematics, as well as the astronomical calendar, and kept detailed records of the movements of the sun and planets.
Zu Chongzhi diligently studied science. His greater achievements were in mathematics. He once annotated the ancient mathematical work "Nine Chapters of Arithmetic" and compiled a book "Fixations".
His most outstanding contribution was to obtain a fairly accurate rate of pi. After a long period of painstaking research, he calculated that pi was between 3 1415926 and the sum, becoming the first scientist in the world to extrapolate the value of pi to more than seven digits.
Zu Chongzhi is an all-rounder in scientific inventions, he has built a kind of guide car, no matter how the car turns, the bronze man on the car always points to the south; He also built a "thousand-mile ship" and tried sailing on the Xinting River (southwest of present-day Nanjing), which could sail more than 100 miles in a day. He also used water power to turn the stone mill and grind the rice and mill the millet, which was called "water milling".

In Grade 6 Mathematics, students learn about decimals and fractions, percentages, integers, graphs and geometry, and algebra and equations.
1. Decimals and fractions: In Grade 6, students will further learn the concepts and operations of decimals and fractions. They will learn how to convert fractions and decimals to and from each other.
For example, students will learn how to convert fractions to decimals, decimals to fractions, and how to add, subtract, multiply, and divide decimals and fractions.
2. Percentages: Students will learn the concepts and representations of analogue percentages. They will understand the relationship between percentages, fractions, and decimals, and learn to add, subtract, multiply, and divide percentages.
For example, students will learn how to calculate quantities that represent percentages, such as tax rates, discounts, or other percentages.
3. Integer: In Grade 6, students will initially learn the concepts of positive integers, negative integers and zeros, as well as the addition and subtraction of integers. In the knowledge of the sixth grade, they will learn how to represent integers on the number line and solve practical problems involving integers, such as altitude changes, temperature changes, etc.
4. Figures and Geometry: Students will continue to learn the properties of figures such as parallel lines, perpendicular lines, polygons, triangles, and quadrilaterals, and calculate perimeters and areas. In Grade 6, they will learn to use different formulas to calculate the perimeter and area of a graph, and explore the characteristics and relationships of the graph.
5. Algebra and Equations: Students will have a preliminary understanding of the concepts and symbolic operations of algebra, learn the solution of unary equations, and perform simple algebraic operations and simplifications. They will learn how to use algebraic formulas and equations to solve practical problems, and develop algebraic thinking and problem-solving skills.
The benefits of studying 6th grade math are as follows
1. Cultivate logical thinking and problem-solving ability: Mathematics is a discipline that requires logical thinking and problem-solving ability. Through Grade 6 Mathematics, students will develop the ability to think logically, learn to analyze and solve problems.
This way of thinking has a wide range of applications in daily life and learning, and can improve students' thinking skills and creativity.
2. Enhance mathematical literacy and mathematics application ability: Learning Grade 6 mathematics can help students build a solid foundation in mathematics and master basic mathematical concepts and skills. This is very important for future learning and life.
Mathematical literacy and the ability to apply mathematics can enable students to better process data and information, solve real-world problems, and be competitive in a variety of disciplines and careers.
