598 ⇒ (5+9) (sum of the first two digit)⇒ 14 ⇒ 14*14(square of the digit) ⇒ 256 ⇒ 196-8(square of the digit - the last digit) ⇒ 188

969 ⇒ (9+6) (sum of the first two digit) ⇒ 15 ⇒ 15*15(square of the digit) ⇒ 225 ⇒ 225-9(square of the digit - the last digit) ⇒216

875 ⇒ (8+7) (sum of the first two digit) ⇒ 15 ⇒ 15*15(square of the digit) ⇒ 225 ⇒ 225-5(square of the digit - the last digit) ⇒ 220
