The Sieve of Eratosthenes is an ancient algorithm for quickly finding all prime numbers within a certain range, proposed by the ancient Greek mathematician Eratosthenes.

Albert Einstein was one of the greatest physicists of the 20th century, came up with the theory of relativity and the energy-mass equation, and won the 1921 Nobel Prize in Physics.

The "bitwise method" usually refers to "bitwise operations," which are low-level calculations that perform logic or shift operations on the binary bits of integers. It's not an independent "counting system" or "number base" (the latter is often mistakenly called "bitwise counting method").

An octagon is a closed shape made up of eight line segments, with a total interior angle of 1080 degrees. It can be a regular octagon or an irregular one, and in everyday life, it’s often used in architecture and sign design.

The octahedron is actually a big family; any polyhedron made up of eight faces is called an octahedron. But the one people usually talk about is the most regular one, the 'regular octahedron.' A regular octahedron is made up of 8 congruent equilateral triangles, has 6 vertices and 12 edges, and looks like two square pyramids joined at their bases.

A percentage is a number that shows what fraction of another number it is, also called a percent or percentage rate. It's a commonly used way to express ratios in math and everyday life, making it easier to compare different data.

Plato (English: Plato, Ancient Greek: Πλάτων, 427 BC (or 428 BC) – 347 BC), originally named Aristocles, was a man born in Athens. He was a great philosopher, thinker, educator, and mathematician of ancient Greece, the founder of Western objective idealism, and one of the greatest philosophers and thinkers in Western culture.

‌最佳拟合线‌是通过数学方法(如‌最小二乘法‌)找到的一条直线,它能最好地代表一组数据点的趋势,使得所有数据点到该直线的误差平方和最小 。

两个或多个整数公有的倍数叫做它们的公倍数,其中除0以外最小的一个公倍数就叫做这几个整数的最小公倍数。

坐标几何‌就是大家熟悉的‌解析几何‌,主要是靠建立坐标系,把几何图形变成代数方程来算 。‌‌
