In the following case, the + means a method in class Int. The following code is a non-conventional method calling syntax:

val add1 = x.+(y)

More formally, the same can be done using the infix syntax, as follows:

val add2 = x + y

Moreover, you can utilize the infix syntax. However, the method has only a single parameter, as follows: ...
