Easy way to multiply large numbers PART-3

Example 1:

108 x 94

Step 1 (I Part). Base is 100 for both numbers.

94      –    6
108    +   8
—————————–
(94 + 8) or (108 – 6) = 102
—————————–

Step 2 (II Part)

(-6) (+8) = (-48)

Step 3

102 / -48

II part cannot be negative. To remove the negative, Subtract 1 from the First part and write the complement of Second Part.

101 / 52

The Answer is 10152.

Example 2:

89 x 114

Step 1 (I Part)

89 – 11
114 + 14
—————————–
(89 + 14) or (114 – 11) = 103
—————————–

Step 2 (II Part)

(-11) (+14) = (-154)

Step 3

104 / -154

II part cannot be negative. Before making the Second part Positive, we must make sure that the number of digits on the Second part is equal to the number of Zeroes in the base. The base is 100.

104 / -154 becomes 103 / -54. (Carry over -1 to the First part)

To make it positive,

102 / 46 (Subtract 1 from the First part and writing complement of the Second part)

The Answer is 10246
