The rules for adding integers also apply to adding rational numbers that are not integers. We review the definitions of integer and rational number. We review the rules for adding integers. We see how the Associative Property of Addition can help us add three addends by grouping two addends with like signs to add quicker. We discuss how we can use brackets as grouping symbols when parentheses are already being used in an equation. We show three helpful hints, which use common sense, to add more than two rational numbers. We group like signs together to add quicker, we look for additive inverses to eliminate them as zero pairs, and we look for compatible numbers that make a whole number. • 7th Grade Math 3.2a, Adding Rational Numbers with the Same Sign, Number Lines • • 7th Grade Math 3.2a, Adding Rational ... • 7th Grade Math 3.2b, Adding Rational Numbers with Different Signs, Number Lines • • 7th Grade Math 3.2b, Adding Rational ... • 7th Grade Math 3.2c, Additive Inverses of Rational Numbers • • 7th Grade Math 3.2c, Additive Inverse... • 7th Grade Math Course • • 7th Grade Math Course • This video and its contents are the property of JoAnn's School and • is protected under U.S. copyright law.
