Operating rules:

Be sure to follow the rule of "multiply and divide first and then add and subtract" from left to right, and count the numbers in brackets first. Various algorithms can be used to make its calculation simpler and more accurate.

(It should be noted that if you encounter several kinds of brackets in an expression, you should count the brackets first, then the brackets, and finally the braces. When calculating, the formulas in brackets should be calculated in the order mentioned above, and then the results should be calculated in the order of numbers outside brackets. )
