In Kotlin, you can perform operations inside a "when" expression by specifying the operation as part of the "when" statement. For example, consider the following code that uses a "when" expression to determine whether a given number is positive, negative, or zero:

val x = 5
when {
    x > 0 -> println("x is positive")
    x < 0 -> println("x is negative")
    else -> println("x is zero")
}
Enter fullscreen mode Exit fullscreen mode

In this code, the "when" expression compares the value of x to different values using the > and < operators. This allows the "when" expression to determine whether x is positive, negative, or zero, and to print the appropriate message.

You can also perform operations inside the branches of a "when" expression. For example, you could use the * operator to multiply x by 2 inside the first branch of the "when" expression:

val x = 5
when {
    x * 2 > 0 -> println("x is positive")
    x < 0 -> println("x is negative")
    else -> println("x is zero")
}
Enter fullscreen mode Exit fullscreen mode

In this code, the first branch of the "when" expression uses the * operator to multiply x by 2 and then compares the result
