Hello all
I missed out at math at school (due to being an idiot) so I am now starting from scratch at 58. I had seen that Serge Langs Basic M<athematics was a good book but I am already stuck at the very beginning which is rather disheartening. I have attached the two sections from relavent pages and just need an explanation of what is meant by:
3 = - (-3)
or
5 = - (-5)
Thank you in advance for any help or ideas
Ian
