... Then we use exactly the same formula as before to associate w with an integer x: x = iknk + ik-1nk-1 + … + i1n1 + i0n0 . With w = 0 we associate the number x = 0. For example, consider the alphabet A = {a, b, c} and the string w = caba. Then x = 333 + 132 + 231 + 1 = 81 + 9 + 6 + 1= 97. Now w ...

... Example 1.6 A chemist has two solutions that contain different concentrations of a certain acid. One is a 3% concentration and the other is an 10% concentration. How many cubic centimeters (cc or cm3 ) of each should the chemist mix to obtain 60 cc of a solution with an acid concentration of 5%? [So ...
