I'd love to hear Little Johnny's answer to that, huh?
Well, why did you came up with this result, XXXnechoXXX
Positive numbers are any numbers greater than zero, for example: 1, 2.9, 3.14159, 40000, and 0.0005. For each positive number, there is a negative number that is its opposite. We write the opposite of a positive number with a negative or minus sign in front of the number, and call these numbers negative numbers. The opposites of the numbers in the list above would be: -1, -2.9, -3.14159, -40000, and -0.0005. Negative numbers are less than zero.
We do not consider zero to be a positive or negative number. The sign of a number refers to whether the number is positive or negative, for example, the sign of -3.2 is negative, and the sign of 442 is positive.
The following fractions are all equal:
(-1)/3, 1/(-3), -(1/3) and - 1/3.
The following mixed numbers are all equal:
-1 1/6, -(1 1/6), (-7)/6, 7/(-6), and - 7/6.
The Number Line
The number line is a line labeled with positive and negative numbers in increasing order from left to right, that extends in both directions, like the one drawn on the blackboard for the kids above. The number line shown below is just a small piece of the number line from -4 to 4.
