An Introduction to Basic Arithmetic Road Signs (BARS)

This BAB (Basic Arithmetic Bit) was created on 21 January 2007 after GDT created the first BARS (Basic Arithmetic Road Sign) for the spring 2007 semester.

In a nutshell, a Basic Arithmetic Road Sign (BARS) is a sign (or group of signs) in which every number in the sign (or group of signs) is used once and only once in a mathematical equation.

Quickie example:

   +-------------------+
   | Fooville        1 |
   | Gootown         2 |
   | Dohvillage      3 |
   +-------------------+

   the numbers are:  1  2  3

   the math is:  1 + 2 = 3

Exponents along with functions such as square root, logarithm, summation, average, and factorial are allowed. The following are used to introduce BARS (Basic Arithmetic Road Signs).

On 15 May 2005, GDT announced that he (along with the characters RoadHacker and TempeHiker) were going start doing BARS. There were 207 BARS as of 21 January 2007.

In some instances, BARS are submitted to RoadSignMath.com (RSM). The RSM motto is: "Driving + Math = Fun."
