What are positive and negative numbers?
Any number above zero is a positive number. Positive numbers are written with no sign or a + sign in front of them and they are counted up from zero to the right on a number line.
Any number below zero is a negative number. Negative numbers are always written with a - sign in front of them and they are counted down from zero to the left on a number line.
Always look at the sign in front of a number to see if it is positive or negative.
Zero, 0, is neither positive nor negative.
