As we can see, the "unary plus" has a priority of`16` which is higher than the `13`of"addition" (binary plus). That's why, in the expression `"+apples + +oranges"`, unary pluses work before the addition.

Let's note that an assignment `=` is also an operator. It is listed in the precedence table with the very low priority of`3`.

That's why, when we assign a variable, like `x = 2 * 2 + 1`, the calculations are done first and then the `=` is evaluated, storing the result in `x`.
