Description

TECHNICAL FIELD

[0001] The utility model relates to the calculator field, more detailed and be related to a calculator based on handwriting formula output result. BACKGROUND

[0002] As a simple, efficient and low-cost auxiliary computing device, the calculator is widely used in daily life, learning and work, and even becomes one of the necessary supplies for learning and office. In the use scene of the calculator, a common scene is that the user needs to additionally prepare paper and pen to record the calculation result while using the calculator. This is because even for simple four arithmetic operations, the calculation result output by the arithmetic calculator is obtained by step-by-step operation according to the input order. For example, for the arithmetic calculator, the sequential input of 2+2×2 will first perform the operation of 2+2, and then perform the operation of 4×2 based on the previous operation result. This operation logic does not conform to the rule of operation based on the priority of operators, so the user needs to perform step-by-step operation on the formula to be operated based on the priority rule of operators, and record the operation result with paper and pen in order to input the operation result in the next operation.

[0003] Although the operation logic of the scientific calculator conforms to the rule of operation based on the priority of operators, for a more complex formula, when the scientific calculator inputs the formula, the input form of the formula needs to be converted to conform to the preset input rule of the scientific calculator. For example, for the formula When the scientific calculator inputs this formula, it needs to be converted to the input form of 6÷ ( 2+3 ) . That is, when the scientific calculator inputs a certain formula for calculation, the input form of the formula may be completely different from the written form of the formula, especially when there is a function operator in the formula. The conversion of the written formula will be more complex and difficult to guarantee the calculation efficiency and accuracy of the calculation result. Therefore, even when using the scientific calculator to calculate the corresponding formula, in order to guarantee the calculation efficiency and accuracy of the calculation result, the user still needs to perform step-by-step operation on the formula to be operated based on the priority rule of operators, and record the operation result with paper and pen in order to input the operation result in the next operation.

[0004] In summary, in the use process of the calculator, it is often necessary to additionally prepare paper and pen to record the calculation result step by step. Some existing calculator manufacturers have developed calculators with a flexible writing screen in the structure to solve this problem, but this type of calculator still needs to perform step-by-step operation on the formula to be operated in use, which is difficult to guarantee the calculation efficiency, and the writing experience of the flexible writing screen is far inferior to that of paper.
