This "book" isn't an explanation of mathematics at all; sure, I can accept that. My biggest qualm is that it isn't even written in Pushtu; sure, it has the same letters. Sure, the vocabulary could be bloody freaking accurate, but this book is written with English grammar, AND from LEFT to RIGHT! (This is a right to left language BTW.) Its like trying to read something below.
.is stupid above book The (the book above is stupid) ~This is written with Pushtu grammar BTW.
.think is it I (I think it is)
Get the picture? Its an absolute waste of time, effort and money. Go elsewhere and don't even spend time considering this worthless book. There wasn't any effort put into it despite the notion otherwise.
