the question might be simple to solve but when entered in google search as:
18/3(5-4+1)
you get 12! However, If it was done using the order of operation it is solved this way:
18 ÷ 3 ( 5 - 4 + 1 )
18 ÷ 3 ( 2 )
18 ÷ 6
= 3
What is the answer? and how can I explain that the other side is wrong? I read about the order of operation but no priority is given in terms of what comes first multiplication or division. So, how is this solved?
The problem you face here is due to the way the equation is displayed, we have
$$ 18/3(5-4+1) $$ which usually means $$ \frac{18}{3}\cdot (5-4+1)=12. $$
The expression you evaluate is $$ \frac{18}{3\cdot(5-4+1)} $$ would be written as $$ 18/(3(5-4+1))=3. $$
Hope this helps.
