I am curious to know as why this statement would print "true"?

[Steven12]

int a = 18;
System.out.println((a == 2 * (a / 10 + a % 10)));

Let's do that calculation part by part,
Due to maths operator precedence, we need to dive into deepest brackets, and after that, we have to calculate step by step
(18 == 2 * (18 / 10 + 18 % 10))
For (18 / 10 + 18 % 10)
18 / 10 -> 1
18 % 10 -> 8, Because it divides 18 by 10, the remainder is 8
8 + 1 = 9
After calculations: 18 == 2 * 9
2 * 9 -> 18
18 == 18 // true
So, that's very normal to be true
