    Yes it would be good using a number line because it shows 2 sides on the line left is negative and right is positive and the middle is both or zero

      How do you know where the negative numbers belong on a number line? Where are they in relation to zero?

      because the negative numbers always go on the left side of the number line.In mathematics, zero is considered to be unsigned, in that it isn't positive or negative. (OHITIKA)

      That is true Devan. Zero is neither negative or positive. Negatives are on the left because they are less than zero.

    On the left side | On the right side
    of the zero is | of the zero is greater than

      Wow Yamni!! You really made me work to understand that reply. I was epically confused when I saw it the first time. You make a valid point about the location in relation to zero.

    Trystan accidentally posted on the wrong post. Here is his response to today's question:
    the number on the left is smaller.

    Since the numbers on a number line increase from left to right, it follows that any number to the left of another number is smaller than that other number

    because a smaller value is on the left of 0 ( zero ).
