Factoring an interest formula 
20200929 

From Kenneth: Hello
P + Pr has a common factor of P so it can be expressed as P(1 + r) after the P is factored out..
How does the "P" get in front of (1 + r)?
P/P + Pr/P = 1 + r What step is used to show that P is added in front of (1 + r)?
I thank you for your reply. Answered by Harley Weston.

Contradiction in the Procedural Precedence and the Distributive property 
20030703 

From Arthur: When complicated expressions exist on both sides of a fraction, and both these expressions contain like and unlike terms with "literal" coefficients, the procedural precedence suddenly gets extremely confusing and seems impossible to simplify. This seems confusing and impossible to simplify because there is a HUGE contradiction in the way Procedural Precedence and the Distributive property deal with Parentheses. The Procedure says you MUST deal with what's INSIDE the parenthesis FIRST, BEFORE dealing with ANYTHING on the outside where as the Distributive property contradicts that by saying to go ahead and ignore the Precedence and use a factor on the outside of the Parenthesis.
