A hexagon is a flat shape with six sides and six angles, and it's very common in everyday life. For example, a bee's honeycomb and snowflake crystals are typical regular hexagon structures, which are not only beautiful but also save materials.

What exactly does 0 mean in math? 0 is the smallest non-negative integer in the set of integers, representing 'nothing' or 'the starting point'.
Quantum physics is a branch of physics that studies the motion laws of microscopic particles. Its core is quantum mechanics and quantum field theory, and it reveals the discontinuity and probability in the microscopic world. Along with relativity, it forms the theoretical foundation of modern physics.
Interest is the extra cost or earnings you get when you borrow or save money—basically, it's the fee for using money.
Three-dimensional shapes are mainly classified based on their shape characteristics and the properties of their surfaces. Common ones include cylinders, cones, and spheres.
A cube root refers to a number that, when multiplied by itself three times, equals the target number. For example, 2 cubed is 8, so 2 is the cube root of 8, written as ³√8=2. Every real number has exactly one cube root.
Cubic units are used to measure the volume of objects and are commonly used in everyday life to describe the space or capacity of containers.
Force is the effect that objects have on each other. It can't exist independently of an object; whenever there is an object exerting a force, there must be an object receiving it.
Theoretical probability refers to the likelihood of an event happening calculated through mathematical analysis under ideal conditions. The core formula is P(A) = m/n. It's based on the axioms of probability theory and includes classic theories like the addition rule and the law of large numbers. Unlike experimental probability, which is based on actual statistics, it's often used in games like dice and poker, as well as in quality control.
