| గుర్తులు | + | - | x | ÷ |
| అర్థం | - | x | ÷ | + |
కాబట్టి, గుర్తులను మార్చిన తర్వాత :
- ఎంపిక - (1) :
96 ÷ 3 + 56 x 16 - 5 = 45 ⇒ 96 + 3 - 56 ÷ 16 x 5 = 45
96 + 3 - 3.5 x 5 = 45
96 + 3 - 17.5 = 45
99 - 17.5 = 45
82.5 ≠ 45 (LHS ≠ RHS)
- ఎంపిక - (2) :
20 + 44 ÷ 11 x 3 - 9 = 30 ⇒ 20 - 44 + 11 ÷ 3 x 9 = 30
20 - 44 + 3.67 x 9 = 30
20 + 33.03 - 44 = 30
53.03 - 44 = 30
9.03 ≠ 30 (LHS ≠ RHS)
- ఎంపిక - (3) :
108 + 3 - 36 x 6 ÷ 15 = 105 ⇒ 108 - 3 x 36 ÷ 6 + 15 = 105
108 - 3 x 6 + 15 = 105
108 + 15 - 18 = 105
123 - 18 = 105
105 = 105 (LHS = RHS)
- ఎంపిక - (4) :
15 - 6 x 15 + 80 ÷ 2 = 25 ⇒ 15 x 6 ÷ 15 - 80 + 2 = 25
15 x 0.4 - 80 + 2 = 25
6 + 2 - 80 = 25
8 - 80 = 25
-72 ≠ 25 (LHS ≠ RHS)
