I am a 7 letter word. Most humans want me. But they hate the first 4 letters of my name. If you get the 2nd, 3rd and 4th letter you are sick. The 5th, 6th and 7th is something with a charge. Who am I?

First dated printed arithmetic book

In 1478, the anonymous Arte dell'Abbaco(“The Art of the Abacus”), printed in Treviso, Italy had this publication date. It is the first dated printed book on arithmetic. The unknown author was likely a priest, and it was dedicated to some of his young friends who kept asking for it. The printer was probably Geradus de Lisa, dé Flandria. The 124-page text dealt with commercial applications of arithmetic, so the language was the local vernacular Venetian dialect, not the scholarly Latin used for the abstract studies of universities. The book teaches the four main operations, with numerous examples, and the concept of fractions (but not the as yet unknown decimals). He shows how to calculate the date of the new Moon. Although some pamphlets on Algorithmus are possibly older than this book, they are undated.«[Image: detail of a calculation shown in the book.]

The new baby

A young mother finds out she is pregnant again, and she tells the good news to anyone who will listen. One day when the woman and the boy are out shopping, a friend of the mother asks the little boy if he was excited about the new baby.

"Oh, yes!" the little tyke says. And having overheard some of his parents' private conversations, he adds, "And I know what we are going to name it, too. If it's a girl we're going to call it Mary, and if it's another boy we're going to call it Quits."
