Hi,

I have a test paper which I am going through but I am struggling on on question, below.

I am not permitted to use a calculator.

Although this would be simple to do in your head, I want to know how I could do it on paper:

30.00

0.86

The answer (yes I cheated, but won't on the actual test) is: 29.14, but I never get this answer when I try and work out this subtraction on paper.

Could someone explain the technique which I need to use to show it on paper?

Thank you.
