4. Addition & Subtraction
8 x (3 + 2)
40
The commutative, associative, inverse, and identity property are properties of which two operations?
addition and multiplication
What property is being shown: (7 + 3) + 9 = 7 + (3 + 9)
Associative Property
A Googol is the number 1 followed by how many zeros?
100 zeros
Which steps in the Order of Operations will you consider multiple operators?
Step 3: Multiplication & Division
Step 4: Addition & Subtraction
9 + 2 x (16 ÷ 4 + 3)
23
What does the commutative property do?
Change the order
What property is being shown: 8 x 1 = 8
Identity Property
What is the only number that cannot be represented by roman numerals?
zero
What is the first calculation you should complete in the following expression:
7 + 2 - 4 + 12 + 3 - 2 + 8 - 9 ÷ 3 x 5
9 ÷ 3
(8 ÷ 4 x 2) + (3 x 4)
18
What does the associative property tell us
Change the grouping
What property is being shown: 8 x 1/8 = 1
Inverse Property
What is the only number, when spelled out in English, is in alphabetical order?
Forty
What is the first calculation I should complete in the following expression:
(7 + 2 - 5) ÷ (5 - 4 + 9)
7 + 2
9 - 7 + 10 ÷ 5 x (9 - 1 x 4)
12
What does the identity property tell us?
a + 0 = a
b x 1 = b
What property is being shown: 7 x 3 x 8 = 8 x 7 x 3
Commutative Property
Recite the first 5 digits of pi (no cheating using the poster on my wall)
3.14159
Come up with your own version of "Please Excuse My Dear Aunt Sally" without using any of the same words.
Mr. Colson's answer: Pink Elephants March Down A Street
23 + 8 x 4 - (12 x 5 - 5) - 12
-12
Provide an example of the inverse property using a reciprocal. Include your solution.
a/b x b/a = 1
Recite all properties of addition and multiplication and what their function is.
1. Associative Property: Changes grouping
2. Commutative Property: Changes order
3. Inverse property: a + (-a) = 0, b x 1/b = 1
