PEMDAS (simple)
1² - 4² =
32
It is the Property demonstrated by this equation:
6 x 8 = 8 x 6
What is the Commutative Property?
9 - 3 x 2=12
Correct answer is 3. Do x then -, not - then x.
2² - (11 – 6)
23
It is the Property demonstrated by this equation:
(2 x 3) x 4 = 2 x (3 x 4)
What is the Associative Property?
52 + 1=11
52 = 25, not 10. Correct Answer is 26.
53
It is the Property demonstrated by these equations:
4 + 0 = 4 5 x 1 = 5
What is the Identity Property?
32 - 6 = 0
32 = 9, not 6. Correct answer is 3
8² - (6 + 30 x 2 – 1) - =
104
It is the Property demonstrated by these equations: 5(3 + 5) = 5(8) = 40
What is the Distributive Property?
4 + 5 + 7 - 3 x 2 = 26
You need to follow PEMDAS and do x first. Correct answer is 10.
10 + (3 x 2)2 - 4 =
32 + 53
It is the Property demonstrated by these equations:
5(3 + 5) = 5(3) + 5(5) = 15 + 25 = 40
What is the Distributive Property?
103 = 30
103 = 10 x 10 x 10, which is 1000, not 30.
