48 SPECIAL TOPICS IN THEORETICAL ARITHMETIC 110. In the binary notation we would count as follows. 1 = wun 10 =ty 11 = tu and wun 100 = four 101 = four and wun 110 = four and tu 111 = four and tu and wun 1000 = eit etc. 111. In the quaternary scale we might count as follows. 11 = wunfy wun 12 = wunfy tu 13 = wunfy three 21 = tufy wun 22 = tufy tu 23 = tufy three o R —~ Il Z e 5 I w < @ = T et e £ 2L T T e Rt T e T SO DA R A TRt TR = R e Il ] o be 0 nine ten, or wunty SO TN UI B WN Il w — " et LT -~ e = po=- - e 10 = four, or wunfy 20 = tu fours, or tufy 30 = three fours, or threefy 112. In the decimal system we may count as follows. 1 = wun 31 = threefy wun 2 =tu 32 = threefy tu 3 = three 33 = threefy three 100 = four fours, steen, or wunsty 101 = wunsty wun 102 = wunsty tu 103 = wunsty three 110 = wunsty wunfy ELeC: 200 = tu steen, or tusty etc. 11 = wunty wun 12 = wunty tu 13 = wunty three 14 = wunty four 15 = wunty five 16 = wunty six 17 = wunty seven 18 = wunty eit 19 = wunty nine 20 = tu tens, or twenty 21 = twenty wun ete.
