Math in the Real World [2/19/1996]
I would like to know some examples of mathematical applications in the real world.

Math Invented or Discovered? [10/26/1999]
Did man create all math? If man created math, then all math can be manipulated, and it is whatever we want it to be, right?

Math is Power? [03/13/2003]
What do people mean when they say that 'math is power'?

Math Symbols [04/07/1997]
What do the common math symbols (backward E, upside-down A, etc.) mean?

Math Used Every Day [11/20/2001]
What type of math do I use every day?

Meaning of the Phrase: Divide by Zero. [01/02/1998]
I want to use 'divide by zero' to indicate a physically impossible task. What does the phrase actually mean?

Meanings of Math Symbols [06/19/1997]
In math notation, what do the vertical bar, the colon, and the solid black square (at the end of a proof) mean?

Mod Function and Negative Numbers [04/28/2000]
What is the correct value for the function MOD(-340,60)? Microsoft Excel returns the value 20, while Lotus 1-2-3 returns the value -40. Can you explain the difference?

More on Order of Operations [02/13/2000]
I have found contradictory information on the precedence of the multiplication and division operations. Is there a universally accepted rule for the order of these operations?

Multiple Solutions [02/08/2002]
Why is there more than one way of doing one type of math problem?

The New Math [07/05/2000]
What is the "New Math?"

Non-terminating Decimal Representations of Fractions [11/10/1997]
Why when you take a finite, limited quantity like one-third and turn it into a decimal do you get .333... on into infinity?

The Orphaned Brace [03/04/2010]
Why do mathematicians format systems of equations with a single, unpaired brace?

Perfect Numbers [11/10/1997]
Do the sums of the digits of perfect numbers always equal 1?

Philosophy of the Truths of Mathematics [02/28/2001]
Do the truths of math hold in any conceivable world?

Point and Line [04/07/2001]
How does something without dimension create something with dimension?

Possible Proof That 1 + 1 Does Not Equal 2 [04/19/2001]
I just want verification... would this proof work?

Precedence of Unary Operators [09/01/99]
The PEMDAS rule for order of operations ignores unary operators. Can you explain the proper precedence for them, and give an example showing how not knowing the rule can cause an incorrect result?

Preparing for a Math Olympiad [12/25/2000]
I want to be a candidate for the International Math Olympiad, and so I have to push way past the subjects covered in class. Do you have any ideas on how I could efficiently "reach the top?"

Project Ideas [06/30/2002]
Can you suggest any science projects involving math and the stock market?

What's the difference between a 'proof' and a 'reason'?

Proving Theorems, Playing Chess, and Remembering Parts [11/23/2013]
Like grandmasters do with chess moves, do mathematicians remember chains of reasoning from one long proof so that they can re-purpose and apply them when proving others? Doctor Ian responds with a number theory example to underscore that memory matters less than insight.

Publishing a Conjecture or Proof, from Due Diligence to Final Publication [06/16/2011]
Does the mathematics community maintain a list of conjectures? or follow some established protocol for submitting new ones? Doctor Vogler explains why no single such collection exists, then outlines the process for vetting and publishing original work.

Quadratic Formula: Solve for b [08/15/2001]
How do you solve for b in the quadratic formula?

Questions About Math [07/31/1999]
