To multiply a two-digit number by two-digit, for example, 97 x 96 requires:
the first 100 - 97 = 3,
the second 100 - 96 = 4,
the third 3 + 4 = 7,
the fourth 100 - 7 = 93.
These are the first two digits of the result.
Next: 3 + 4 = 12.
These are two second digits of the multiplication result.
So, 97 x 96 = 9312.

Щоб перемножити двоцифрове число на двоцифрове, наприклад, 97 х 96 потрібно:
перше 100 - 97= 3,
друге 100 - 96= 4 ,
третє 3 + 4= 7,
четверте 100 - 7= 93.
Це дві перші цифри результату.
Далі: 3 + 4= 12.
Це дві другі цифри результату множення.
Отже, 97 х 96= 9312.
