We have learned +, -, *, / these four operations. It is now stipulated that "*" is a new operation, A*B means 3A-2B, and the order of operations takes precedence over multiplication and division. Such as: 6/4*3=1. So how much is 5+3*2=.
我们学过+、-、*、/这四种运算．现在规定"*"是一种新的运算，A*B表示3A-2B，且运算顺序优先于乘除．如：6/4*3=1．那么5+3*2=多少．
