Nearly the whole of the detailed working of the particular example in which S = 5, t = 6, s = 3 and b = 4, is preserved. It is substantially as follows: St = 30; S - s = 5 - 3 = 2; 2(S - s) + b = 8; 2(S - s) + b² = 64; 8St = 240; 8Stb = 960; 2(S - s) + b² + 8Stb = 1024; √1024 = 32; 32 + 8 = 40; 40 ÷ 8 = 5 = x.
