a/ 997 + 86 = (1000 - 3) + 86
= 1000 + 86 - 3
= 1086 - 3
= 1083
b/ 37 . 38 + 62 . 37 = 37 . (38 + 62)
= 37 . 100
= 3700
c/ 43 . 11 = 43 . ( 10 + 1) = 43 . 10 + 43 . 1 = 430 + 43 = 473 ;
67 . 101 = 67 . (100 + 1 ) = 67 . 100 + 67 . 1 = 6700 + 67 = 6767 ;
423 . 1001 = 423 . ( 1000 + 1) = 423 . 1000 + 423 . 1 = 423000 + 423 = 423423
d/ 67 . 99 = 67 . (100 - 1 )
= 67 . 100 - 67 . 1
= 6700 - 67
= 6633
e/ 998 . 34 = (1000 - 2 ) . 34
= 1000 . 34 - 2 . 34
= 34000 - 68
