She's in year 2 
I over-complicate things....here is what it says exactly
The Great Fire of London was in 1666
use the numbers 1666 to find:
The highest number by adding them together
The lowest number by taking them away
can you find any other number stories?
I obviously understand the adding part...but the taking away confuses me...
Taking them away from what? DO I take the relt from the addition..19...and add 9 and 1 together? Or am I missing something?
Sorry for my dimness! I got a U in GCSE maths and still find it frightening...I have not asked DD if SHE understand it yet as I don't' want her to share my fear of maths...so I want to understand it before I try to help her complete it alone.
