First, you need to know… Associative Property of Addition When: (a + b) + c = a + (b + c) Commutative Property of Addition When: a + b= b + a Zero Property of Addition When: a + 0= a
4,285 + 124 Always start with the ones.
Let’s Try Some! 4,285 + 124 4,409 2,402 +1,789 4,191 1 11
More Practice! 1,891 + 298 2,189 5,765 + 6,341 12,106 11 11
4,987 - 2,158 Always start with the ones.
Let’s Try Some! 4,987 - 2,158 3,230 - 320 177 212 2,829 1,910
More Practice! 5,290 - 1,488 9,222 - 6,180 412810 112 3,802 3,042

PROPERTIES REVIEW!. MULTIPLICATION PROPERTY OF EQUALITY.
Algebraic Properties Learning Goal: The student will be able to summarize properties and make connections between real number operations.
Basic Laws Of Math x
Chapter 1-4: Properties Commutative Property: the order in which you add or multiply numbers does not change the sum or product Ex = * 8.
Quiz Review Properties and Integers Operations with Decimals Addition Subtraction Multiplication Division.
RATIONAL NUMBERS RATIONAL NUMBERS The numbers of the form p/q (q=0) is called a RATIONAL NUMBER. Examples: 5/7 6/8 -6/9 etc. RATIONAL NUMBERS. PROPERTIES.
Properties of Operations in Math Lesson 2. Inverse Operations Means: “putting together” a problem and “taking it apart” using the same numbers by + and.
Lets Review Integers (you do not need to write this part down)
Adding Integers. Zero Pair = 0 Why it works… __________ Property says you can add or subtract zero without changing the value of an expression.
Algebra II Honors Properties Review Chapter 1. We will solve 2x + 4 = 6x – 12 Showing all of the properties used So Let’s go!
Properties of Real Numbers 1.Objective: To apply the properties of operations. 2.Commutative Properties 3.Associative Properties 4.Identity Properties.
Properties and Scientific Notation
Properties of Addition
WHEN MULTIPLYING LIKE BASES, YOU ADD THE EXPONENTS FOR EXAMPLE:
Properties are special qualities of something. Addition and multiplication have special qualities that help you solve problems mentally = MENTAL MATH!!
Algebra I Sections 2.2, 2.3, 2.5, 2.7. Properties of Addition Commutative Property a + b = b +a a + b = b +a 3 + (-2) = (-2) = Associative.
Solving Linear Systems By Elimination. Solving Linear Systems There are three methods for solving a system of equations: By Graphing them and looking.
