What is the closure property of addition?
a. The sum of two positive real numbers will be a unique real number.
b. The sum of any two integers will always be an integer.
c. The sum of any two rational numbers will always be a rational number.
What number would make the number sentence true? 4+(?+6) = (4+3)+6
Both -5 and 11 are integers, and their sum (-5 + 11 = 6) is also an integer. This follows the _________ Property.
7/2 is a fraction, and adding it to an integer (4) could result in a fraction, a mixed number, or an integer, depending on the value. Therefore, it is not guaranteed to be an integer. Does this follow the Closure Property?
__________ of addition: Changing the order of addends does not change the sum.
3+4=7, so 4+3=
11
7
9
8
8+2=10, so 2+8=
8
2
10
12
2+7=9, so 7+2=
9
12
15
2
6+8=14, so
6+8=14
14+6=8
8+6=14
7+7=14
7+9=16, so
16-9=7
9+7=16
9+9=16
7+9=16
8+1=9, so 1+8=9
Which property is this?
True or False: The associative law of addition states that for any three real numbers a, b, and c, the expression a + (b + c) is equivalent to (a + b) + c.
Which of the following expressions demonstrates the associative property of addition?
a) 3 + (7 + 2)
b) (3 + 7) + 2
c) 3 + 7 + 2
d) All of the above
If a = 5, b = 8, and c = 2, evaluate both sides of the equation to determine if the associative law holds: a + (b + c) = (a + b) + c.
a) 15 = 15
b) 15 = 20
c) 15 = 13
d) 15 = 17
True or False: The associative law of addition applies only to real numbers and not to subtraction.
True or False: The associative law of addition holds for any three real numbers, regardless of their values.
If a = 4, b = 2, and c = 7, evaluate the expression (a + b) + c and determine if it is equal to a + (b + c).
a) True
b) False
c) Cannot be determined with the given values
d) Both sides are always equal
