如何向我的聊天机器人添加计算器

Question

I need help to make my chatbot have the ability to calculate simple math problems (+,-,*,/).

Answer 1

Take the value from the chat, in this case a command to calculate, say [calc](calculationhere) then parse the equation with a library. A simple search will yield many javascript calculation parsers for simple operations like with that fashion.
