Integers Integers – all whole numbers and their opposites. Real-world examples of integers: Elevations: Above sea level (such as Mount Rainier in Washington at 14, 410 ft) – positive integers Below sea level (such as Death Valley, CA at 282 ft) – negative Temperatures: above and below zero (78⁰ Money/Checking Account: and -14⁰ ) deposits – adds money to your account (positive) withdrawls – take money from your account (negative) Football: yardage can be positive or negative Absolute value: a number’s distance from 0 on the number line - write it as |-3| - think … how far is this number from 0? Operations with Integers Adding Integers: 1. Separate – circle numbers and signs 2. Check signs (same signs – Add / different signs – Subtract) 3. Take the sign of the BIG BOY Subtracting Integers: 1. Add the opposite 2. Check signs (same signs – Add / different signs – Subtract) 3. Take the sign of the BIG BOY Multiplying or Dividing Integers: 1. 2. Multiply or divide (without signs) Check signs same signs – the answer is positive different signs – the answer is negative
