Questions and suggestions

 * What point on the surface of the Earth is farthest from the center of the Earth?
 * Is the answer the same as the highest point of elevation on the surface? As in the tallest mountain? Ender  and  Peter  17:33, 27 June 2015 (UTC)
 * No, the farthest point from center of the Earth considering that the Earth is oblate.  Buaidh  13:17, 28 June 2015 (UTC)
 * Answer: The summit of Chimborazo in Ecuador.  From 1531 until about 1820, Chimborazo was widely thought to be the highest mountain on Earth.


 * What point on the surface of the Earth is closest to the center of the Earth?
 * Answer: The North Pole, or if you consider the seafloor to be the surface of the Earth, the Polar Deep.


 * What number is one greater than its multiplicative inverse?
 * If the multiplicative inverse of any non-zero real number is always 1, I suppose that 2 would be one more than 1? I'm getting back into math lately, so I had to go for this one. I'm trying to brush up on my algebra, calculus, and discrete math. Ender  and  Peter  17:33, 27 June 2015 (UTC)
 * This is actually a first year algebra problem. The multiplicative inverse of 2 is 1/2, so it would be a number less than 2.  You may need to use the the quadratic formula, which gives two answers.   Buaidh  13:17, 28 June 2015 (UTC)
 * Oh, I see. I was referring to a particular list titled Properties of Real Numbers from a book called College Algebra: Graphs and Models (ISBN 978-0321791009) and its description for the Multiplicative Inverse property is the formula that says any real number multiplied by its inverse is 1, so that's what I meant by saying the multiplicative inverse of any non-zero real number is always 1. I see how in this question, and I suppose generally, the term "multiplicative inverse" refers to a non-zero real number's own reciprocal, or inverse, rather than to the result of applying the property. The book also describes the Multiplicative Identity property as a formula stating that a real number multiplied by 1 is the original real number. The multiplicative inverse article here describes the multiplicative identity as another way of saying 1. I see how in both cases in the book, the name of the property is based on the factor by which the real number is multiplied. Alright, I will try to find those answers. Ender  and  Peter  13:23, 30 June 2015 (UTC)
 * Answer: X = 1 + 1/X = 0.5 ± √1.25 = the Golden Ratio (1.6180339887498948482) and its negative conjugate (-0.6180339887498948482).


 * What U.S. state changed its name after it became a state?
 * Answer: In 1780, the State of Massachusetts Bay changed its name to the Commonwealth of Massachusetts, following the lead of the Commonwealth of Pennsylvania and the Commonwealth of Virginia.


 * What Colorado town has the lowest ZIP code?
 * Answer: Arvada CO 80001


 * Fortunately, you don't need any of the answers to attend the Wiknic.
 * Suggestion: Next year, let's hold our Wiknic on the first Sunday on or after July 9 so we don't conflict with the Independence Day holiday or LGBT events in June.   Buaidh  12:11, 1 July 2015 (UTC)
