1. Overview of pocket calculator manufacturing
a. What is a pocket calculator?
- A pocket calculator (calculator) is a type of electronic device used to perform basic arithmetic and algebraic calculations. Pocket calculators are small in size, and are often designed to be carried in a pocket or purse. The features of pocket calculators can vary, from simple functions such as addition, subtraction, multiplication, and division to more complex features such as percentage calculations, statistical calculations, and scientific calculations.
- Pocket calculators are commonly used to solve simple calculations in daily life, or in fields such as mathematics, accounting, economics, and science. In addition, pocket calculators are also widely used in education, in the teaching of mathematics and other subjects. Currently, with the development of technology, many features of pocket calculators have been integrated into mobile devices such as smartphones and tablets.
- In Vietnam, the pocket calculator manufacturing industry has not developed strongly, and the market is mainly occupied by foreign brands.
- According to statistics from the General Department of Vietnam Customs, the import of pocket calculators into Vietnam from 2016 to the present has not changed significantly, with an average of about 50,000 units imported each year, with a value of 150,000 to 200,000 USD. These imported products mainly come from Japan, China, and Taiwan.
- However, with the development of technology and the demand for pocket calculators in education and research, the pocket calculator manufacturing industry in Vietnam has the potential to develop further in the future.
