What is 8 less than a number z

Answer 1

Hi Ana.

8 less than the number z

As we know, "less than" means we need to take away, or subtract.

So, if it 8 less than the number z, we need to take 8 away from z, or subtract 8 from z

So our answer would be 8 - z

Please remember - a common mistake here is you may hear "8 less than z" an remember less than means subtract, so many students will just plug that right in like "8 - z" but this is not the answer - remember its 8 LESS THAN Z so you need to take 8 AWAY from z, not the other way around.

Hope this helps!
