    negative number greater than zero

    Are negative numbers greater than zero?
    We assume that negative numbers are smaller than zero, according to previous definition.
    In this case we discuss the (1)-(2) = (-1) on the coordinate axes.
    Assuming -
    ​.........................................< --------------
    -5------4------3-------2-------1------0-------1-------2-------3----------------------------------------> ∞
    The direction for positive numbers as we know is left to right.
    And right to left for subtraction. (The red arrow)
    If we assume the observer on (-5):
    When the observer looks at subtraction sign, concludes that because it is a subtraction its direction should start from (-5) to right (positive numbers directive) of the coordinate access from the observers point of view ,(-5) same zero ,(-4)same one ,(-3)same two ,(-2)same three ,(-1) same four ,
    (0) same five , (1) same six , .and etc.
    Actually according to this subtraction, the meaning of numbers is disappeared.
    In definition, numbers are measured from zero,
    For example: the (-1)starts from zero and continues to (-1),but according to this subtraction ,here the number(-1)starts from (-5)and continues to (-1).
    when we say:
    -5<-4<-3<-2<-1<0<1<2<3<..
    The numbers have lost their meaning.
    If we put their equivalents; from the point of the observer ,we will see that we have changed the numbers to positive numbers ,with this replacement,
    0<1<2<3<4<5<6<7<8<9<
    {0=-5,1=-4,2=-3,3=-2,4=-1,5=0,6=1,7=2,..}
    If we generalize this numbers to (-∞) we have:
    (- ∞) same as zero , (zero) same as (+∞)
    (+∞) same as (2∞)

    Then we observe that according to this subtraction, the nature of negative numbers has been lost, and
    Turned to positive numbers, and in fact while we assume negative, they are positive numbers.

    Actually the left-to-right direction means inceasing values, but not necessaruily positive: -1 is to the right of -2 not because -1 is (t's not), but rather because -1 is greater than -2.

    OK - this is true for subtracting positive numbers, not negative.

    You lost me there. Why would an "observer" on -5 conclude that subtraction means moving to the right? That woud be true if subtracting a negative number, but not if subtracting a positive number. Are you limiting this discussion to subtracting negative numbers?

    Huh? I'm not following you at all.

    OK.

    Sorry - I have no idea what you're trying to say, and in fact the rest of your post is unintelligible.

    I believe you have misunderstood the meaning of interpretation of the set of real numbers R with the points of a line ...Please study it again.
    Meanwhile the infinity is a dynamic meaning in Math and not a number to interpret and use as the common numbers are used.

    Re: negative number greater than zero

    just keep one thing in mind that on a number line a number to the left of a number is smaller than it and a number to the right of it is greater than it. The starting point is 0.

    if assume negative number less than zero,then dimension zero are extreme
