Question

Which statements are true according to the order of operations?

Choose exactly two answers that are correct.



A.


32 + 8 ÷ 4 = 40 ÷ 4 = 10


B.


4 + 12 ÷ 2 = 4 + 6 = 10


C.


12 + (6 ÷ 3) = 18 ÷ 3 = 6


D.


(20 – 5) • 3 = 15 • 3 = 45

Answer 1

b is correct (Parentheses Exponents Multiplication/Division Addition/Subtraction) divide comes before add also d because parentheses are before multiplication

Answer 2

A is incorrect because if you follow PEMDAS, the answer to the left side of the equation is 34:

8/4 = 2
32 + 2 = 34

B is correct since when you follow PEMDAS, since the answer to both sides is 10:

12/2 = 6
4 + 6 = 10

C is false because the left side equals 14 when following PEMDAS:

6/3 = 2
12 + 2 = 14

D is correct because when you follow PEMDAS, the answer on both sides is 45:

20 - 5 = 15
15 * 5 = 45

So the correct answers are B and D! Hope this helped u! :)
