### MEAP Preparation - Grade 7 Mathematics1.134 Properties of Addition in Integers

 Property I: For any two integers a and b, their sum a+b is also an integer. Examples: 1. 3 + (-4) = -1 2. (-4) + (-5) = -9 Property II: For any two integers a and b, a+b = b+a. Examples: 1. 2+(-6) = (-6) + 2 = -4 2. (-3) + (-4) = (-4) + (-3) = -7 Property III: For any three integers a, b, and c; a+(b+c) = (a+b)+c. Example: 1. (-2)+[4+(-5)] = [(-2)+4]+(-5) = -3 Property IV: For any integer a; a+0 = 0+a = a. Here, zero is called the identity element under addition of integers. Examples: 1. 0+(-4) = -4 2. 5+0 = 5 Property V: For any integer a; a+(-a) = (-a)+a = 0. Here, -a is called the additive inverse of the integer a. Examples: 1. 1+(-1) = 0 2. (-4)+4 = 0 Directions: Answer the following questions. Also write at least five examples for each property of your own.
