Let the number be 'x' Half of 'x' is written as x/2 To take '7' away we write ''(x/2) - 7 ' Note the use of brackets, because if written as 'x/2 - 7 ' are we subtracting '7' from '2' only. So the brackets give clarity that the '7' is being subtracted from the term inside the brackets, which is 'half of 'x''.
