Arithmetic operators

We can perform arithmetic operations using the arithmetic operators. Arithmetic operators contain operators for addition (+), subtraction (-), multiplication (*), division (/), and remainder (%). We've already seen many examples for addition, not mentioning that these operators are methods!

Let's take examples of others:

scala> val x = 10 - 1
x: Int = 9

scala> val y = 10 * 1
y: Int = 10

scala> val z = 10 / 1
z: Int = 10

scala> val yx = 10 % 9
yx: Int = 1

These operators have their overloaded versions also defined, to see that we may try with different types as operands. Let's take an Int and Double:

scala> val yx = 10 % 9.0
yx: Double = 1.0

Here, the first operand is an Int, and the second one is a Double, and since Int is view-bounded to Double, the result is converted to Double.
