FORMAL versus INFORMAL INFORMATION:
Formal Information systems–are based on the supposition that we can identify individual’s information requirements and that we can also determine the methods of producing information from data to satisfy these requirements.
Examples of formal information include:
Legal requirements, government legislation, union contracts, accounting procedures, planning requirements, organizational budgets, job demands, communication requirements, control needs, stockholders and creditor demands, problem solutions, and general decision-making processes, paychecks, invoices, purchase orders, and receiving tickets and all examples of structured forms of formal information. In Contrast,
Examples of informal information include:
Opinions, judgments, hunches, intuitions, hearsay, personal experiences, “grapevines,” “rules of thumb,” gossip, assumptions, and so forth.
Both types of information may be essential to the management and operation of an organization, but formal information is the only valid output
... Programming are not designed to take roots of negative numbers. For example, the cube root of – 8 is – 2, but the programming expression (–8)^(1/3) will not give this value. Programming expressions such as A^B will result in an error if A is negative and B is not an integer.
4. The LET Statement: Assigning Values to Variables
In section 3.3 you learned how to write arithmetic expressions in a form acceptable to the computer. Now we will show you how to instruct the computer to evaluate such expressions.
A programming line consists of an instruction to the computer

Good stuff dude.
