Calculator ideas 1. Input formula required2. Whether the test formula contains letters3, if the inclusion of letters will need to re-enter, otherwise the next operation4, detection of the existence of parentheses, if there is parentheses, the value of the parentheses inside the priority operation, and then assigned to the original position, no then the priority operation, the result of the final operation is taken out Flow chart 650)

Recently, I am busy with some web-related things, namely, HTML + CSS + JavaScript applications. I think these little things are very interesting. I can exercise my hands-on skills and consolidate my knowledge. It is a pity to leave it on the hard disk. Therefore, share it with you and give it a reference to the children's shoes you need. In fact, the level of food is still very good, and these things are not practical at all, because I tried to be compatible only with Firefox and Google, a
