Hi all,

Can someone help with this BODMAS question? The answer is 205, according to the Bond book but it's not what I'm getting!

Pls set out your explanation. TIA!

17-3x2+(4sq - 3)x5

Sorry don't know how to set out 4 to the power of 2, which is what I mean by 4sq. I am really starting to think that the answer they've given is wrong...

you can do this 4^2 - that is 4 to the power of 2

brackets - 16-3=13
brackets * 5 = 65

then 3x2=6

so sum becomes

17-6+65= 76??
