Addition combines values to make a total. 2 Correct! Addition combines values to make a total. 3 100% means the whole amount. 4 Correct! Addition combines values to make a total. 5 Correct! Addition combines values to make a total. 6 Correct! Addition combines values to make a total. 7 C is the Roman numeral for 100. 8 Correct! Addition combines values to make a total. 9 Correct! Addition combines values to make a total. 10 Correct! Addition combines values to make a total. 11 Correct! Addition combines values to make a total. 12 Correct! Addition combines values to make a total. 13 10 × 10 = 100. 14 100 = 2^2 × 5^2, so only 2 and 5 are prime factors. 15 100 decimal equals 1100100 in binary. 16 Water boils at 100 degrees Celsius at sea level. 17 A century equals 100 years. 18 100 = 2^2 × 5^2, so nontrivial factors include 2 and 5. 19 100 ends with an even digit, so it is even. 20 Digits: 1 + 0 + 0 = 1. 21 A standard deck has four suits with 13 cards each, totaling 52. 22 The false shuffle is designed to look random but control order or arrangement. 23 Riffle shuffles split the deck and interleave the halves. 24 A true random shuffle aims to remove any order pattern. 25 There are 4 cards of each rank in 52 cards, giving 4/52 = 1/13 for a match. 26 Overhand shuffle is quick but not always perfectly random; casinos use more complex methods. 27 The Mongean shuffle has a distinctive top-to-bottom transfer pattern. 28 Magicians use false shuffles to control order while looks chaotic. 29 Seven perfect riffle shuffles restore the original order (GSR theorem). 30 Shuffling randomizes card order to prevent manipulation or prediction.
