How does Kotlin evaluate this expression?

val x = 2
val y = 3
val z = x + y * x - y / x

What is the value of z?

A4

B7

C5

D6

Step-by-Step Solution

Solution:

Step 1: Calculate multiplication and division first
y * x = 3 * 2 = 6; y / x = 3 / 2 = 1 (integer division).
Step 2: Evaluate addition and subtraction left to right
x + 6 - 1 = 2 + 6 - 1 = 7.
Step 3: Re-check integer division
In Kotlin, integer division truncates, so 3 / 2 = 1.
Final Answer:
7 -> Option B
Quick Check:
Multiplication/division before addition/subtraction [OK]

Quick Trick: Integer division truncates decimals [OK]
