Step 4: All operators are binary, which means that the first operand is positioned before the operator, and the second operand is positioned after the operator.

步骤4：所有的操作符都是二元的，也就是说第一个操作数位于操作符之前，第二个操作符位于操作符之后。

youdao

The syntax is OK in the sense of, it is an operand, an operator, an operand, so syntactically it's OK.

这里的语法应该是好的，有个运算对象，一个运算符，另外一个运算对象，因此语法上是没错的。

youdao

Because the operator returns its left-hand operand, we can combine a sequence of input requests into a single statement.

由于输入操作符返回其左操作数，我们可以将输入请求序列合并成单个语句。

And in Python the expression is, operand, operator, operand, when we're doing simple expressions like this, and if I give it to the interpreter, it gives me back exactly what you'd expect, which is that value. OK?

在Python中表达式就是，运算对象，操作符，运算对象，当我们处理这样的简单表达式的时候，我把表达式传给处理器，处理器给我返回了我想要的结果，对不对？
