3 In numeris ab unitate consequentibus, summa cuius libet multitudinis ad aliam summam alterius multitudinis, si ab utraque dimidium maximi numeri auferatur, est ut quadratum multitudinis unius ad quadratum alterius multitudinis. Summa enim ab est 36, ablato dimidio 8, remanet 32; summa ac est 21, ablato dimidio 6, remanet 18: et 32 ad 18 est ut quadratum multitudinis ab, nempe 64, ad quadratum multitudinis ac, quod est 36.
C01 128 + 256[0] + [?]800 = [?]488
C02 66 - 5 1/2 = 60 1/2
128_60 1/2 = 256_121
256 * 60 1/2 = 15360 + 178 = 15538
C03 11 * 11 = 121
C04 66 - 5 1/2 = 60 1/2
128_60 1/2 = 256_121
128 + 1560 + 12800 = 14488
C05 16 * 16 = 256

a 1 + 2 + 3 + 4 + 5 + c 6 + 7 + b 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 = 136
C07 136 - 8 = 128
