Evaluate :-$150 ÷ [66 ÷ 11(26-23)]$.

Question

Evaluate :-$150 ÷ [66 ÷ 11(26-23)]$.

This question is present in my brother's mathematics book. I followed BODMAS rule and got the answer but the book has a different answer and not following the proper order. I have shown my steps below. Please verify if I am wrong or the book's answer is. Thank you!

$150÷[66÷11(26-23)]$

$\rightarrow 150÷[66÷11(3)]$

$\rightarrow 150÷[6×3]$

$\rightarrow 150÷18$ $= \frac{15}{18} = \frac{25}{3}$ .

However the answer shown in the book is $75$.

Please Reformat the Question . It is difficult to read them like that . — Anonymous, Sep 08 '20 at 15:44

For $[66\div11\{3\}]$ multiplication comes before division.

Can you please explain why multiplication comes before division here? Because if we follow the order we need to go from left to right and divison comes first here. – Best Bibek Sep 08 '20 at 15:52
There is a detailed discussion in the link above. – player3236 Sep 08 '20 at 15:55

If the book says the answer is $75$ then it is referring to $150\div [ 66\div \{11(26-23)\}]$. You can see that formatting the operation as I did previously is not as "problematic" as formatting it like this: $150 ÷ [66 ÷ 11(26-23)]$
