    The largest negative integer is the negative integer that is greater than all other negative integers. hence -1. Hopefully this isn't devolving into a political conversation.

    I’ve given up trying to be calm. However, I am open to feeling slightly less agitated. I’m begging you for the benefit of everyone, don’t be STUPID.

    Check this out. It's JavaScript but...

    Number.MIN_VALUE < -1 // true
    Number.NEGATIVE_INFINITY > -1 // false
    // a little clearer
    -1 > Number.NEGATIVE_INFINITY // TRUE

    So the largest negative integer is -1. :thumbsup:

      So which is bigger: -1 or -2?

        What is the smallest positive integer minus the largest negative integer?

        Yeah, I resorted to asking a child. The smallest positive integer is 1. I can cope with that. The largest negative integer is infinite. She said infinite negative +1. I am still looking for a way to refute that.

            Largest negative. I had not noticed that. Reading correctly is half the battle. :thumbsup: Well done :suss:

              I fell for the same. -1 is larger than -10. The largest negative integer is -1. Infinity isn't in this game. Made me feel stupid and I loved it :thumbsup:

                All depends on one's definition of largest negative integer. The largest integer that is negative or the largest negative integer compared to all negative integers. The problem as stated is missing this clarity.

                  This was my answer as well. Both the smallest positive and largest negative integers are 0. But I can see the case for both 2 and Infinity. Brent Hoskisson

                    For sure: if I have -$2, I owe the bank more than if I had -$1. $2 is a larger number, indicating a larger debt.

                        I think it's a bad mistake to assume that a computer implementation of a mathematical concept provides a correct definition, especially at the limits. But I agree that mathematically -1 is larger than -2. It's the distance from the extreme left of the number line (-infinity) that illustrates this. And zero is neutral, neither positive nor negative. And we're relying on ChatGPT for truth now? Lord help us!

                            The smallest positive integer is either 0 or 1 depending on whether 0 is considered positive or not. The largest negative integer is -1. So the answer is 1 or 2. This is not the intent of question but that is the correct answer given how the question was worded.

                              I thought the same thing. Also, isn't it interesting that on the other side of 0 that no one had a problem distinguishing the smallest positive integer : which is 1. Aren't all numbers greater than others when the are further to the right of other numbers? Also, do these people not believe that following are true? -5000 < -1 -1 > -5000 Then why don't they know that the largest negative integer is -1?

                                Halfway through my first cup of coffee, this sent me into overthink mode, coming up with everything from infinity to zero. It took some reading of comments to see the correct answer is indeed 2. Great question Griff.

                                        Since this is a coding site here are the possibilities for a 32-bit int.

                                        #include #include int main()
                                        {
                                        int pos = 1;
                                        int neg = INT_MIN;
                                        printf("pos=%d neg=%d\n", pos,neg);
                                        printf("pos+neg=%d\n", pos+neg);
                                        printf("pos-neg=%d\n", pos-neg);
                                        printf("neg+pos=%d\n", neg+pos); // yes I know it's commutative but here for completeness
                                        printf("neg-pos=%d\n", neg-pos);
                                        return 0;
                                        }

                                        pos=1 neg=-2147483648
                                        pos+neg=-2147483647
                                        pos-neg=-2147483647 // Hmmm...this seems wrong -- subtracting negative SHOULD add it.
                                        neg+pos=-2147483647
                                        neg-pos=2147483647

                                          Is zero positive?

                                          Depends on context. See Is zero positive or negative?
