I attended a TED speech this morning: I used computers to teach my children real mathematics. The speaker first proposed that students learn mathematics more and more boring, while mathematicians feel that they know and understand the mathematical knowledge and their limitations.

expression is not used. (Execution efficiency is not necessarily high compared to other algorithms, and is only used to verify that the program's processing power is enhanced through rules, and that the regular expressions and program logic are not rigorously written without deep validation due to no in-depth testing)In fact, although the program is very simple, but, in fact, is a simple rule of the prototype engine.First, he loads a lot of business processing rules, plus, minus, multiply, divi
