Пример 8. Сложим десятичные числа 15 и 6 в 2-, 8- и 16-ичной системах счисления.
Двоичная система: 11112 + 1102 = 101012

Ответ: 15 + 6 = 2110 = 101012 = 258 = 1516
Проверка. Преобразуем полученные суммы к десятичному виду:
101012 = 24 + 22 + 20 = 16 + 4 + 1 = 21
258 = 2*81 +5*80 = 16 + 5 = 21
1516 = 1*161 + 5*160 = 16 + 5 =21
