From the most primitive abacus to the calculation applications on modern smartphones, each tool represents a change in the times and carries our memories and thoughts on technology. First, there was the abacus. As a classic calculation tool in ancient China, the abacus was once an essential item in every home and school. With its simple structure, it provided convenience and accuracy through the movement of beads for addition, subtraction, multiplication, and division calculations. In the era of limited technology, the abacus was an indispensable part of people's lives.

Secondly, mechanical calculators gradually entered our lives with the advancement of technology. These calculators use gears and lever principles to perform calculations, providing a more convenient and efficient way compared to the abacus. They became a powerful assistant for people to perform complex calculations in schools and offices.

Then came the electronic calculator, which gradually became popular in the electronic age. These calculators use electronic components to perform calculations, offering both speed and accuracy. The emergence of electronic calculators greatly improved people's calculation efficiency and made complex mathematical calculations easier. Finally, with the development of mobile internet and computer technology, our current calculation tools have undergone tremendous changes. Smartphones and computers now not only have powerful computing capabilities but also integrate various application software such as Excel, MATLAB, etc., which can easily solve various complex mathematical problems. At the same time, the emergence of various online calculation tools has also made our calculations more convenient and efficient. In conclusion, the evolution of calculation tools has witnessed the development of technology over the years. Each tool we have used has left a unique imprint on our memories, marking the progress of science and technology.
