Question: 7 less n
Answer: 7 - n
z - 7
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''.
"< 0" For example x < 0 means "x less than zero".
