Сумму всех целых чисел от 1 до 100 можно посчитать при помощи хитрого приема. Разобьем все числа по парам 1 и 100, 2 и 99, 3 и 98 и т.д. Сумма каждой пары 101. Пар всего 100 пополам (50). Поэтому сумма равна 2(1+100)100.
Для нечетного количества слагаемых работает та же формула: например, 1+2+3=2(1+3)3=6.
