I have got the answer to my confusion . When parenthesis are there , multiplication sign is invisible . But is implied that we must take into consideration . So , the 2nd method is correct .
Just now I came across a math problem . Looks simple. After learning from mistake of previous problem , I applied BODMAS rule to solve the problem .
Problem
6 ÷ 2 ( 1 + 2 ) = ?
I solved like this :
First , sum inside the bracket.
( 1 + 2 ) = 3
Now , 2 ( 3 ) is 2 × 3 = 6
Now , 6 ÷ 6
Answer is 1 .
This is what I learned in school . But there is a new approach to solve this problem . Answer is different .
Now I said parentheses means multiplication . So our new form of problem is like this ,
6 ÷ 2 × 3 = ?
Applying BODMAS ,
Division comes first . Then multiplication
So ,
6 ÷ 2 = 3
Now , problem is reduced to ,
3 × 3 = 9
Final answer : 9 .
The method I used is a common practice method . The next method is what people use nowadays . But interpretation of problem is different . I guess the 2nd interpretation is correct . But I am confused totally .
