The way that the problem is written leaves it open to the question of how do you do it. Do you first add 200 to 939494884 and then divide that answer by 848432?
.
The rules of algebraic operations contain the following procedures:
.
Read the problem from left to right and do the multiplications and divisions in the order that you encounter them. Enter the results for each as you do them.
.
Then read the problem again from left to right and do the additions and subtractions as you encounter them. Enter the results for each as you do them.
.
According to these rules read this problem from left to right, skipping all the additions and subtractions that might be involved and the first multiplication or division you encounter is the division:
.
"939494884/848432"
.
Do that division and, to 8 decimals, you get the answer of:
.

.
Replace the division with its answer and the problem then becomes:
.

.
That takes care of all the multiplications (there were none) and the single division involved. Next you read the problem from left to right with the completed division:
.
"200 + 1107.33079846"
.
And you encounter the single addition (no subtractions encountered). Do that single addition by adding the 200 to the results of the division and you get the answer of:
.

.
That's the answer.
.
The person who wrote the problem did so by presenting it as a single line entry of:
.
"200+939494884/848432"
.
and and it was up to you to decide in what order to work it. That made it necessary for you to understand and apply the rules governing the order of operations. It would have been easier to work if the author of the problem had written it as:
.

.
That way of writing it makes it pretty clear that the number 939494884 is to be divided by 848432. And the 200 is to be added to the quotient.
.
Hope this helps you to understand a couple of the rules that apply the order of performing algebraic operations.
