1. What is a Trig?

   1.   ?    "a rule with scales for solving trigonometry problems (S, ST, T)"
   2.   ?    "a rule with the trigonometric scales (S, ST, T) marked in degrees and tenths of a degree"
   3.   ?    "a rule with scales for raising numbers to powers. (Scales usually started with LL)"

2. When was the logarithm that led to the slide rule discovered?

   1.   ?    1468
   2.   ?    1249
   3.   ?    1200
   4.   ?    1614

3. What is a Duplex?

   1.   ?    "the single sided rule similar to a Polyphase but with and inverted A scale (typically labeled R) instead of an inverted C scale (CI)"
   2.   ?    "a double-faced rule. Typically added three folded scales (CF, CIF, DF) to those of the Polyphase rule to make many problems easier to solve"
   3.   ?    "a rule with that read both common and natural logs"

4. Who discovered the logarithm that "made it possible to perform multiplications and divisions by addition and subtraction"?

   1.   ?    John Napier
   2.   ?    William Oughtred
   3.   ?    Edmund Gunter

    2.   ?    "a rule with the trigonometric scales (S, ST, T) marked in degrees and tenths of a degree"
    3.   ?    "the single sided rule similar to a Polyphase but with and inverted A scale (typically labeled R) instead of an inverted C scale (CI) "
