78 - 5 x 9 + 5 Is 38 but I thought BIDMAS meant you would do 45 + 5 and then take it away from 78 making the answer 28? Can someone explain?

78 - 5 x 9 + 5      multiplication/division  takes precedence over addition/subtraction as we move from left to right

 

So......we want to first multiply  5 x 9 = 45   .....so we have

 

78 - 45 + 5      now....just add/subtract as normal

 

33 + 5 =

 

38
