CSI Algebra: Variables &ExpressionsDetectives,As you know we are after a group of international evil geniuses, the Mathemagicians. Our evidenceindicates they have plans to build a world conquering device – to conquer the world. It seems that oneof the anonymous henchmen, Otto Pemdas, has committed a string of robberies all over Australia. Wefear this is another step in the Mathemagician’s attempt to build a world conquering device.Fortunately, the Mathemagicians are arrogant about their work and havea reputation for leaving behind a trail of notes and a cryptic text message.The text message when substituted correctly will calculate to the Otto’sfavorite number. So far there are six suspects that police havequestioned. It is hoped that someone with a relatively strong numbersense can crack some codes that have puzzled the detectives on the caseso far.Your job is to bring Otto Pemdas to justice and save the planet. You needto be prepared to state your case and demonstrate your understanding ofthe following skills that Otto is known to use in the notes.-Order of Operations-Translating Verbal and Algebraic Expressions-Open Sentences-Distribution-Combining Like TermsBe sure to include:-Other examples of the concepts-Definitions-Any other relevant information.This is not a time to be sloppy. The slightest miscalculation or illegible footnote could result in a notguilty verdict. Oh, did I mention that use of a calculator might prematurely set off his world conqueringdevice? Good luck to you, gumshoe.Chief Harris 21st Century Math Projects

CSI Algebra: Real NumbersDetectives,A thief, working under the alias Guapo Arcsin, has caused a ruckus all throughout Central America. It isbelieved that Guapo is a member of the evil genius group, the Mathemagicians. From what thedetectives have gathered thus far from the previous thefts, the Mathemagicians are building a worldconquering device.Fortunately, Guapo has left behind a trail of notes and a cryptic text messagethat he has told us will calculate toward his favorite number. Thus far there aresix suspects that police have questioned. It is hoped that someone with arelatively strong number sense can crack some codes that have puzzled thedetectives on the case so far.Your job is to bring Guapo to justice and save the planet. Since you are beingbrought in as a specialist you have to have definitive proof in order for any arrestto hold up in court.You need to be prepared to state your case and demonstrate your understandingof the following skills that Guapo is known to use in her/his notes.-Square root approximation-Decimal, fraction, percent, conversion-Scientific Notation-The Real Number SystemBe sure to include:-Other examples of the concepts-Definitions-Any other relevant information.This is not a time to be sloppy.

CSI Algebra: Solving EquationsDetectives,Once again the world has been rocked by a string of high profile robberies. This time it seems theMiddle East has been victim of the evil genius group, the Mathemagicians. Notes signed “Kareem AlJabr” have been discovered at each of the robbery sites. Once again a cryptic text message was sent,but requires the puzzles to be cracked. We believe the Mathemagicians have been successfully piecingtogether a world conquering device.Again we’ve been told the result of the cryptic text message willcalculate to Al-Jabr’s favorite number. Thus far there are sixsuspects that police have questioned. It is hoped that someonewith a relatively strong number sense can crack some codes thathave puzzled the detectives on the case so far.Your job is to bring Al-Jabr to justice and save the planet. You needto be prepared to state your case and demonstrate yourunderstanding of the following skills that Al-Jabr is known to use inthe notes.-Translating equations-Solving equations-Using FormulasBe sure to include:-Other examples of the concepts-Definitions-Any other relevant information.This is not a time to be sloppy.
