Answer 1

the correct order of operations is

1.  replace the parenthesized group by the sum 10

2.  now it says 20 divided by two multiplied by ten.

3.  since both division and multiplication are involved, and their priorities in PEMDAS are equal, therefore the order of these two operations must be done in left-to-right order.

4. thus the 20 divided by two is performed, giving ten, and finally, then,

5. we have 10 times ten which is the result 100.
