Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a calculator that emphasizes the thinking process, which solves the problem that the existing calculator proposed in the above background technology only pays attention to the calculation results, and cannot show the calculation process for primary school students, which is not conducive to students' improvement. Computing ability, secondly, general calculators need to use power supply during use, resulting in a large amount of battery usage and a waste of power

The invention discloses a calculator attaching importance to the thinking process, which relates to the technical field of calculation equipment for primary school students. The calculator specifically includes a base, movable rods and stainless steel cylinders. Vertical support rods are fixedly installed on the left and right sides of the upper surface of the base. A lower transverse frame is installed below the vertical support rods. Each vertical support rod is provided with a circular hole inside. The upper ends of the movable rods pass through the insides of the circular holes respectively. Connecting blocks are arranged outside circular slots respectively. An inserting rod is fixed integrally at the lower end of each movable rod. The left and right ends of the stainless steel cylinders are integrally connected with the outer surfaces of the connecting blocks. The device pays more attention to the calculation process, and enables students to see the detailed calculation process and steps more clearly during learning and better understand the calculation of addition, subtraction and multiplication. Primary and secondary school students will not waste a lot of paper and pen resources, and the learning time of primary and secondary school students is saved. Moreover, students have a better and quicker understanding of the calculation content, and the practical ability of students is enhanced.
Description
technical field [0001] The invention relates to the technical field of computing equipment for primary school students, in particular to a calculator that emphasizes thinking process. Background technique [0002] When elementary school students calculate addition, subtraction and multiplication, they take draft paper and pens, which is very troublesome. After a month, they need to use a lot of draft paper and pen water, resulting in a lot of waste of paper. Therefore, elementary school students also use calculators to For auxiliary calculation, a calculator is a modern handheld electronic machine that can perform mathematical operations. It has an integrated circuit chip, but its structure is much simpler than that of a computer. It can be said to be the first generation of electronic computers (computers), and its functions are also weak. The power source of the inverter is an AC converter or a battery, and the battery can be recharged with an AC converter or a solar conve...
