Problems solved by technology

[0003] However, the calculation functions of current mobile phones are simple addition, subtraction, multiplication, and division, which cannot perform mathematical calculations or judge the correctness of mathematical calculations. Therefore, users use this common mobile phone to perform a series of mathematical calculations. When calculating the calculation formula (such as: 100×((50+18)÷2)), you must first calculate 50+18 and then record the result of 50+18, so that the result can be continued to ÷2, and then put The result after ÷2 is recorded, so that the result can be multiplied by 100 to obtain the final result. Therefore, the user must record many intermediate values, which is very inconvenient

Embodiment Construction

[0009] The present invention is a calculation method for mathematical calculation formula of a mobile phone. The method is to set various mathematical calculation symbols (such as: +, -, ×, ÷, ()...etc.) in the mobile phone, and these calculations The sequence of calculation of symbols, when the user enters a mathematical calculation formula in the calculation function of the mobile phone, the mobile phone will judge whether the mathematical calculation formula is correct according to the mathematical calculation symbols and the calculation order of these calculation symbols Mathematical calculation formula, if it is a correct mathematical formula (such as: 100×((50+18)÷2)), then calculate the mathematical formula, and then display the calculation result through its screen, if the mathematical calculation If the formula is not a correct mathematical calculation formula (such as: 100×(50+18)÷2)), an error message (such as: please re-enter the input error message) will be display...

Abstract

The invention relates to a method for a handset to calculate arithmetic formula, setting various arithmetic signs in the handset and their calculated sequence, and as a user inputs an arithmetic formula in the calculation function of the handset, the handset at once judges if the arithmetic formula is an exact one: if yes, the handset calculates the arithmetic formula and then displays the calculated result on the screen; otherwise displays an error message on the screen to prompt the user to reinput an arithmetic formula.

Description

technical field [0001] The invention relates to a calculation method for a mobile phone to perform mathematical calculation formulas, in particular to a method for enabling users to perform general mathematical calculation formula calculations in the mobile phone. Background technique [0002] In today's fast-paced urban living environment where every second counts, the mobile phone is not only used as a fast and convenient communication tool, but also has many software attached to it, such as: game software, phone book, voice mail call, computer, alarm, Connect to the Internet (WAP), transmit short messages, etc., to provide users with additional services, effectively improve their use functions, and meet users' needs for one machine with multiple functions. [0003] However, the calculation functions of current mobile phones are simple addition, subtraction, multiplication, and division, which cannot perform mathematical calculations or judge the correctness of mathematica...
