(a) 1234 x 567 - 234 x 567
= 567 (1234 - 234)
= 576 (1000)
= 5,76,000
(b) ( 70) (10 - 5 - 22 - 83)
= (70) (100)
= 7,000
(c) 739 x 99 - (- 739)
= 739 × 99 - (-739) × 1
= 739 × 99 + 739 × 1
= 739 (99+1)
= 739 (100)
= 73,900
(d) 861 x (-3) + (-861) x 7
= 861 × (-3) - 861 × (-7)
= 861 (-7-3)
= 861 (-10)
= - 8,610
(e) 326 x (- 108) + 326 x 8
= 326 (-108+8)
= 326 (-100)
= - 32,600
(f) 242 x (- 95) + 242 x 4 - 242
= 242 x (- 95) + 242 x 4 - 242 × 1
= 242 (-95+4+1)
= 242 (-90)
= - 21,780
