You Can Add!
Two or more numbers that are added to find a sum
Remember: Commutative Property of Addition Changing the order of addends does not change their sum. Ex. A + B = B + A
Associative Property of Addition The grouping of addends does not affect their sum. Ex. (a + b) + c = a + (b + c)
a+ (b+c) = (a+b)+c
5 + (3+4) = (5+3) +4 5+ 7 = 8+4 12 = 12
a+(b+c)= (a+b)+c 2+ (1+5)= (2+1) +5 2+6=3+5 8=8
Use the following numbers to create your own addition problems using the associative property of addition. 2, 3, 4 5, 6, 2 8, 1, 3
Did you do the following? 2+ (3+4)= 92+3) +4 5+ (6+2) = (5+6)+2 8+ (1+3) = (8+1) +3
Addition using three addends. An associative property is when you group numbers in anyway and the answer stays the same.
1.4 PROPERTIES OF REAL NUMBERS I CAN IDENTIFY AND USE PROPERTIES OF REAL NUMBERS.
Properties of Real Numbers
Adding and Subtracting Whole Numbers and Money Fact Families.
Adding Integers. Adding Integers with the Same Sign Add the absolute values. The sum will have the same sign as the addends. Example 1 Find –2 + (-3)
Multiplication properties. Multiplication properties.
Taks Objective 2 Properties and attributes of function.
Adding and Subtracting Integers To add integers with the same sign, add their absolute values and then change the sign to the sign of the addends. Positive.
Properties of Algebraic Notation

Adding and Subtracting Rational Numbers 2-2 Objective: Students will add and subtract integers and rational numbers. S. Calahan 2008.
1.2 ADDING AND SUBTRACTING INTEGERS I can find the sums and differences of integers by using a number line or using SSA/DSS.
© 2007 M. Tallman. Commutative Property © 2007 M. Tallman The order of the addends does not change the sum = addends sum =
Distributive Property. The property that states that multiplying a sum by a number is the same as multiplying each addend in the sum by the number and.
Lesson 3: Properties of Addition and Multiplication Pages:
Properties of Addition and Multiplication. Commutative Property In the sum you can add the numbers in any order. a+b = b+a In the product you can multiply.
Find the sum or difference. Then simplify if possible.
