Then you 'add' five multiplied to 'b' , then you subtract two multiplied to 'c' and the whole '2c' is divided by '3'. The divisional three only refers to the '2c'. If you wanted to divided the whole expression by '3' , then you insert brackets. [ 6a^(2) + 5b - 2c ] /3 Note the position(s) of the 'square brackets'.
