Instruction: Let us determine how much you already know about properties of integers, fractions and decimals. Read each item carefully Provide the correct answer by writing it on your answer sheet.

For items 1 to 7, identify the property of operations on integers being illustrated in each mathematical expression.
1) (-12)(1) = -12
2) (11 + 7) + 2 = 11 + (7 + 2)
3) 13 + 1 = 1 + 13
4) 7 (2 + 6) = (7)(2) + (7)(6)
5) 21 + 34 = 55
6) (-117) + 0 = -117 7) 39 + (-39) = 0 Choices: a) closure property
b)commutative property
c)associative property
d) distributive property
e) identity property
