# Negative Numbers?

Jason, Emma, Denzel, Carlos, and Chen were discussing negative numbers.

Jason: “I think negative numbers are like ordinary numbers but with a negative sign.”

Emma: “Negative numbers are amounts less than 0.”

Chen: “I think of negative numbers as movements on a number line.”

Denzel: “Negative numbers are like debts, when you owe money, and positive numbers are like credits, when you have money.”

Carlos: “I do not think there is any such thing as a negative number. You can’t count negative numbers.”
