Mono Monday 122 Crunching numbers

This week's MM  theme, set by Nickimags888,  is numbers.  Numbers are something that I have seen plenty of today and indeed many of my working days! Excel is  my best friend, well almost:  I do still use a calculator and for the last 15 years have always used this rather childish looking calculator which usefully doubles as a pencil box and is solar powered.  I seem to recall that I pinched it from daughter #1 somewhere along the line!

Not an exciting image to be sure, but one which sums up my day.
