(1). 498 × 17 + 498 × 13
♦ By taking 498 as common
= 498 ( 17 + 13)
= 498 (30)
= 14940
(2) 66193 + 7×1
= 66193 + 7
= 66200
(3) 569 × 114 + 569 × 13 + 569 × 70
= (569 × 114) + (569 × 13) + (569 × 70)
♦ By taking 569 as common .
= (569)(114 + 13 + 70)
= (569)(197)
♦ Well as we are able to see multiplication by 197 is hard so we will take it as (200 - 3)
= (569)(200 - 3)
= (569 × 200) - (569 × 3)
= 113800 - 1707
= 112093
(4) 438 × 999 + 438 × 1
♦ By taking 438 as common
= 438(999 + 1)
= 438(1000)
= 438000
(5) 375196 × 1265 - 1265 × 265
= (1265 × 375196) - (1265 × 265)
♦ By taking 1265 as common
= 1265( 375196 - 265)
= 1265(374931)
= 474287715
