Abacus is an ancient computing tool, which has made an important contribution to mathematics education. First of all, the abacus is an important invention in ancient China, and its appearance greatly promoted the development of mathematics. In ancient times, people used abacus to carry out all kinds of complicated calculations, such as addition, subtraction, multiplication, division, square root, etc., which provided a basis for mathematical research.

Secondly, the use of abacus helps to cultivate students' logical thinking ability and spatial imagination ability. Through the operation of abacus calculation, students can intuitively understand the relationship between numbers and master the operation rules, which plays an important role in improving students' mathematical literacy.

Thirdly, the use of abacus also helps to cultivate students' patience and carefulness. When abacus calculation is used, it needs to be done step by step, without any carelessness, which has a positive impact on cultivating students' good study habits.

In addition, as a traditional computing tool, the existence of abacus is also helpful to inherit and carry forward the excellent traditional culture of China. By studying and using abacus, students can understand the wisdom and talents of ancient China, and enhance their national pride and cultural self-confidence.

Generally speaking, the contribution of abacus to mathematics education is mainly reflected in promoting the development of mathematics, cultivating students' logical thinking ability and spatial imagination ability, cultivating students' study habits, and inheriting and carrying forward Chinese excellent traditional culture. With the development of science and technology, abacus has been replaced by electronic calculators and computers, but its role in mathematics education can not be ignored.
