Mathematical Meltdown!

For people of a certain age these books bring back memories.
You need to see the font and layout of the text in these books - its unbelievable! Small and all scrunched up, even looking at it now its difficult to make head or tails of whats going on!
These books are totally responsible for my complete lack of mathematical understanding to thus day. Even as I took these books out of the cupboard I found my hands shaking and a light sweat formed on my brow. For me these books do bring back memories - but not good ones!
