Answer» 24 × 26 + 154 × 146 – 384 ÷ 12 =? Or, ? = 624 + 22484 – 32 = 23076 Or, we can CALCULATE it like following – ? = $(\left( {25 - 1} \right) \times \left( {25 + 1} \right) + \left( {150 + 4} \right) \times \left( {150 - 4} \right) - {{384} \over {12}})$ = (25)² – (1)² + (150)² – (4)² – 32 = 625 – 1 + 22500 – 16 – 32 = 23076

Answer»

24 × 26 + 154 × 146 – 384 ÷ 12 =?

Or, ? = 624 + 22484 – 32

= 23076

Or, we can CALCULATE it like following –

? = $(\left( {25 - 1} \right) \times \left( {25 + 1} \right) + \left( {150 + 4} \right) \times \left( {150 - 4} \right) - {{384} \over {12}})$

= (25)² – (1)² + (150)² – (4)² – 32

= 625 – 1 + 22500 – 16 – 32

= 23076
