Z is the first letter in the German words “zahl”=number or “zahlen”= to count.
Because the German Universities dominated mathematics in the nineteenth and early twentieth century, Z became the symbol for the integers.
I feel stupid asking but I have a homework question that asks to describe the "z" number system. Does anyone care to explain waht this is and include 3 examples? My guess is that its the integer system but i have no idea.
thank you.
