Thank goodness for YouTube and Long Division!

Yup, this evening the inevitable happened... I turned to google to find a video that explains how to do Grade 5 long division.  Sure, I did Mathematics as part of my first studies at in a Bachelor of Science degree at WITS many, many, many years ago... And, yes, I devoted quite a substantial portion of one of the chapters of my doctoral research (in fact a critical part in the argument of my PhD) to a complex set of mathematical equations that have to do with Strong Artificial Intelligence and Cognitive Neuroscience... Yes, yes, yes... 

BUT, these are different times!  The dendrites in my little old brain are calcifying and Mathematics is more difficult in the 5th grade than it was in my PhD... Ha ha, either that, or I have complete forgotten how to do Mathematics without a calculator!

The task was simple - write 1/8 as a fraction...  Mmmmmm... It took me a while to remember how to do that.  Of course the answer (which took me a while to work out) is this:

1/8 = 1/8 * 125/125 = 125/1000 = 0.125

I know some of you are laughing... But, when you pick yourselves up off the floor you might want to watch this little 'refresher' video long division (without a calculator) to help your kids get their homework done!

Seriously though, it is SUCH a blessing to help Courtney to catch up with her Maths after the 8 weeks she had off from the time of hear hospitalization, through her surgery, up to her recovery and return to school!

I do, however, praise and thank God for YouTube!
