AN 2.1 Extending Addition to Rational Numbers How can you predict if the addition of two numbers will be positive, negative, or zero? Vocabulary Toolkit: algorithm A set of rules for performing a procedure. 1/5 + 2/10 = 2/10 + 2/10 = 4/10 = 2/5 absolute value The distance of any number from zero. │6│= 6 │-6│= 6

As a table team, answer the questions from your packet 2.1. ======== ======== packet

======== ======== all the problems are addition the sign is the same for both numbers being added the answer is the sum of the two numbers all the problems are addition the sign are different for both numbers being added the answer is the difference of the two numbers

+ ADD NUMBERS WITH DIFFERENT SIGNS 1.Ignore the signs and subtract the two numbers. 2.Give the answer the sign of the greater Absolute Value 5‾1‾1

Positive + Positive = Positive Negative + Negative = Negative Positive + Negative = Negative + Positive = 1. Find the difference (ignore the signs) 2. Take the sign with the greater Absolute Value Adding Integers
