1. + और *
⇒ 16 * 4 ÷ 2 + 12 - 4 = 40
⇒ 16 * 2 + 12 - 4 = 40
⇒ 32 + 12 - 4 = 40
⇒ 44 - 4 = 40
⇒ 40 = 40
2. + और -
⇒ 16 - 4 ÷ 2 * 12 + 4 = 40
⇒ 16 - 2 * 12 + 4 = 40
⇒ 16 - 24 + 4 = 40
⇒ 20 - 24 = 40
⇒ -4 ≠ 40
3. ÷ और *
⇒ 16 + 4 * 2 ÷ 12 - 4 = 40
⇒ 16 + 4 * 6 - 4 = 40
⇒ 16 + 24 - 4 = 40
⇒ 40 - 4 = 40
⇒ 36 ≠ 40
4. ÷ और +
⇒ 16 ÷ 4 + 2 * 12 - 4 = 40
⇒ 4 + 2 * 12 - 4 = 40
⇒ 4 + 6 - 4 = 40
⇒ 10 - 4 = 40
