Welcome to Math-Center.Org’s Signed Numbers page, where students learn to work confidently with positive and negative numbers in both real-world and mathematical situations. Signed numbers are numbers that include a plus (+) or minus (–) sign to show their direction or value in relation to zero. Positive numbers are greater than zero, while negative numbers are less than zero. These are used to represent things like temperatures below freezing, bank withdrawals, or moving down a staircase. In the middle school curriculum, students learn to compare, order, and perform operations with signed numbers, as well as apply them on the coordinate plane. Mastering signed numbers is essential for developing number sense and preparing for algebra. This page includes explanations, examples, and practice activities to help students build confidence and accuracy with positive and negative values.
