what

[remote radish]

int add(int a, int b) {
    int max = 2147483648;
    return max - ((max - a) - b);
}

[unborn lake]

max could be anything, this is just doing max - max + a + b

[remote radish]

wdym?

[unborn lake]

well I mean that you can set max to whatever, the underlying math is just max-max+a+b which is just a+b

[remote radish]

it only has subtraction

and the max is the signed int maximum

Bruh

Don't drop math it's important

What is substraction but the addition of the opposite

[remote radish]

Huh

[exotic marten]

this is why learn math

[frosty forum]

Yup learn math man,
Max-((max-a)-b)

Max-(max-a-b)
Max-max+a+b
(Max-max)+(a+b)
(0)+(a+b)
Just, (a+b)

[remote radish]

Yes; that’s the point

[wicked juniper]

This has nothing to do with integer overflow

And if u are surprised by -(-x)=x perhaps u should go back to kindergarten

[remote radish]

I was trying to make an add function with only subtraction

[wicked juniper]

Have u tried x - (-y)

How old are u

[remote radish]

Yes

No
