What is the correct answer to 20÷2(5+5)?

20 ÷ 2 (5 + 5) = 100.

In the 1500s the specific rules of the order of operation were promptly issued. The order of these workings states which processes take precedence (as a key priority) before which other operations.

Operation priorities are as follows.

Let's implement the rule.

Add 5 by 5 in parentheses.

Properly apply rule number 3 from the priority operation above. Initially, we have to divide 20 by 2 which is the result of 10

Continuing with multiplication 10 by 10.

So, the correct answer is

Notes:

What is the result if we don't follow operation priorities? Let's see.

At this crucial point.

We decide to multiply 2 by 10, even though there are no parentheses from them, only parentheses for 10.

Therefore, the incorrect answer is

That's what happens if we don't follow operating priorities.

Unless the problem like this (see the parentheses carefully):  

Thus, the difference must be considered. Consistently, obey the priority of the operation and look at the problem in detail.
