CHAOS  Created Havoc Amongst Orthodox Scientists 
Angela Brett 
CHAOTIC  Can't Highly Accurately Observe These Iterative Creations. 
Angela Brett, after reading about the mathematical phenomenon chaos... it's all about sequences which seem totally random but are generated by a simple mathematical rule  however, slight changes in the starting values can drastically change the whole thing, so chaotic motion is still very difficult to predict. 
CODE (2)  Confusingly Ordered Diatribe, Enigma 
Gavin Lambert Communication 
DECIMAL POINT  Dot Emphasising Change In Magnitude... Any Leftward Part's Obviously Integral, Nearby's Tenths.

ENCRYPTION  Each New Code Requires Your Powers To Interpret Others' Notes. 
Angela Brett Computers 
HAM SANDWICH THEOREM  Here's A Mathematical Statement Anyone (Not Dealing With Integrals) Can Hungrily Test. Halve Exactly Outer Rolls, Even Meat. 
Angela Brett (From the Collins dictionary of Mathematics: ham sandwich theorem, n, a colourful name for the theorem that given three volumes in Euclidean threespace, there is at least one plane which simultaneously bisects the three volumes. As a consequence, any sandwich may be cut in such a way that the two pieces have equal amounts of filling and equal amounts of each slice of bread.) Food & Drink 
INFINITY  Increment Numbers Forever  It's Nuts, I Tell You! 
Angela Brett 
INTEGRATION PROJECT  It's Not Too Easy Getting Result... Adding That Infinity Of Negligible Parts. Relying On Just Exhaustive Calculation's Terrible!

PRIME  Produce Right Integers Multiplying Eternity 
Charles H. Montgomery, Jr. 
PRIME POWERFUL NUMBERS!  Positive = Recursively Invoke (Multiplication * {Each Prime, One Withheld!} ^ Exponent). Represent Factorisation Uniquely, Luminescing Naturals Unlimited! "Mathematics By Expansion: Reduces Swiftly!" 
Charles H. Montgomery, Jr. In apronym, PRIME is a transitive verb. One Withheld! means that mathematicians do not define ONE as a PRIME, even though PRIME commonly means FIRST. ONE is called a UNIT. "Mathematics By Expansion: Reduces Swiftly!" fractions. Fundamental Theorem of Arithmetic n. Every natural number is either prime or may be decomposed uniquely into prime factors. 
PRIMES  Positively Represent Individuals! Multiply Essential Services!

Charles H. Montgomery, Jr. Sum 30Day Month Numbers: 4(April)+6(June)+9(September)+11(November)=10+20=30 (!) One of my original discoveries when I was less than 45. (Halves {Initial = Remotest  Two} Year): First Half of Year ==>(Initial=4) = (Remotest=6)  2. Last Half of Year ==>(Initial=9) = (Remotest=11)  2."Four (Regeneration Increases!)
