In ancient times, people gradually explored the methods of physical counting, knot counting and trajectory counting in their lives. The counting method of primitive society shows how to check the number of sheep returning from grazing with pebbles at that time; Count the number of prey by tying rope; Record the fishing amount by carving on wood and so on. Later, word counting and abacus counting were invented one after another. Now, we only use the number combination like 1234567890 to represent any quantity-related equivalence. How lucky and proud we are.

In life, mathematics is everywhere, and numbers are everywhere. From birth to death, we have been dealing with numbers all our lives. Everything from astronomy to geography is inseparable from mathematics.

Through the calculation of numbers, we put on clothes that fit us; Through numerical calculation, we live in a solid house; Through numerical calculation, we know how high the sky is and how deep the sea is. Through calculation, we learned to adapt to and transform nature.

The existence of decimal point may be invisible dust; The existence of a decimal point may also be our distance from the sun and the moon.

Mathematics is the progress of mankind. I am amazed at the magic and profoundness of mathematics. Now, we can only start with the most basic addition, subtraction, multiplication and division, and with care, perseverance and endurance, step by step, actively explore the mysteries of mathematics that we have mastered and failed to master, and enjoy and create our brilliant life with mathematics.
