Mathematical Expressions in Scala in Scala

We can perform multiple calculations using operators in the same line of code:

println(3 - 4 + 6) // Prints 5
println(5 + 2 - 3) // Prints 4
println(2 * 5 + 1) // Prints 11
println(4 / 2 * 5) // Prints 10

We can also use variables:

var num1 = 5
var num2 = -1

println(2 * num1 * num2) // Prints -10
println(num1 + num2 - 3) // Prints 1
println(20 / num1 + num2) // Prints 3
println(num1 / 5 * num2) // Prints -1
