Dollar Sign
Origin: When the U.S. government begin issuing its own money in 1794, it used the common world currency - the peso - also called the Spanish dollar. The first American silver dollars were identical to Spanish pesos in weight and value, so they took the same written abbreviations: Ps. That evolved into a P with an s written right on top of it, and when people began to omit the circular part of the p, the sign simply became an S with a vertical line through it.

Equal Sign
Origin: Invented by English mathematician Robert Recorde in 1557, with this rationale: "I will settle as I doe often in woorke use, a paire of paralleles, or Gmowe [i.e., twin] lines of one length, thus : , bicause noe 2 thynges, can be more equalle." His equal signs were about five times as long as the current ones, and it took more than a century for his sign to be accepted over its rival: a strange curly symbol invented by Descartes.

Question Mark
Origin: When early scholars wrote in Latin, they would place the word questio - meaning "question" - at the end of a sentence to indicate a query. To conserve valuable space, writing it was soon shortened to qo, which caused another problem - readers might mistake it for the ending of a word. So they squashed the letters into a symbol: a lowercased q on top of an o. Over time the o shrank to a dot and the q to a squiggle, giving us our current question mark.

Exclamation Point
Origin: Like the question mark, the exclamation point was invented by stacking letters. The mark comes from the Latin word io, meaning "exclamation of joy." Written vertically, with the i above the o, it forms the exclamation point we use today.

Olympic Rings
Origin: Designed in 1913 by Baron Pierre de Coubertin, the five rings represent the five regions of the world that participated in the Olympics: Africa, the Americas, Asia, Europe, and Oceania. While the individual rings do not symbolize any single continent, the five colors - red, blue, green, yellow, and black - were chosen because at least one of them is found on the flag of every nation. The plain white background is symbolic of peace.
