9 + (1 + 5)² divided by 3 + 3 x 2

I checked the answers at the back of my textbook, and it's somehow 5. What I need to know is how they got there.

Any help is appreciated.

This is a question you could make simple errors .. you need to use BIDMASS or BODMASS

So 9+(1+5)²  is equal to 45

You first add 1 and 5 which gives you 6.. then square 6 which gives you 36.. then add this to 9..

then you divide 9 by the bottom..

So here is where people tend to make mistake..

First you do 3 x 2 then you add the answer to 3

this is because multiplication comes first in BIDMASS then addition..

the answer should be 9 ( 3 x 2= 6 ... 6+3 = 9 )

then you simply divide 45 by 9 giving you 5

hope that helps.. x

9 + (1 + 5)² divided by 3 + 3 x 2

Bidmas (brackets, indices, division, multiplication, addition, subtraction) in that order
Break it up 9 + (1 + 5)²
1. Brackets (1 + 5) = 6
2. Indicies (1 + 5)² = 6² = 6 x 6 = 36
3. 9 plus (1 + 5)² = 9 + 36 = 45

Then 3 + 3 x 2
1. Multiply, as m is before addition in the word bidmas. So first 3 x 2 = 6
2. Then addition 3 + 6 (we found the 6 from above) = 9

Finally 9 + (1 + 5)² which we found = 45 divided by 3 + 3 x 2 which we found = 9
45 divided by 9 equals 5.
