Question

Which statements are true according to the order of operations?

Choose exactly two answers that are correct.



A.


7 • 6 + 4 = 7 • 10 = 70


B.


16 – (4 + 7) = 12 + 7 = 19


C.


10 + (6 ÷ 3) = 10 + 2 = 12


D.


2 + 5 • 7 = 2 + 35 = 37

Answer 1

It's C and D.
................

Answer 2

To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
