The state of California uses a mechanism known as NOTS.

NOTS stands for Negligent Operator Treatment System.

What is this:

It is a program that is known to rehabilitate chronic violators of the driving laws in California. It consists of a series of computer generated warning letters and sanctions against violators. It affects drivers with age 18 years old and above in California.

How it works:

The actions in this program are based on "negligent operator points" that is being recorded every time period. These are added continuously until it reaches a certain degree which it needs an administrative hearing. Points are being assigned depending on the degree of the offense. It would range from zero to three points.

The term gram formula mass is synonymous with molecular mass. So, to get this, we must add molar mass of all the elements in this compound.

Given compound is Lithium Sulphate - Li2SO4

Elemental calculation ::

Li  -  Lithium   -   6.941    -     2   -   13.88200 %
S  -  Sulfur     -    32.065   -    1   -   32.065 %
O  -  Oxygen   -   15.9994  -    4   -   63.9976 %

Now, total = 12.6264 + 29.1647 + 58.2090 = 109.9446 

Hence, the gram formula mass of Li2SO4 = 109.9446.

The required number 100.

It is not an odd number and is not higher than 100 and greater than 90.

When we subtract 100 from 100, we get nothing i.e, 0.
