Subtraction of Large Numbers
To subtract a number from a given number, you must take the following steps :
« Arrange the given numbers in columns as you have arranged for addition.
« Begin with ones, go on subtracting columnwise, borrow if necessary, from the next
column to the left.
Example : Subtract 256 million 126 thousand 924 from 7 billion 39 million 125
thousand 620.
Solution : 7 0 3 9 1 2 5 6 2 0
– 2 5 6 1 2 6 9 2 4
6 7 8 2 9 9 8 6 9 6
Thus, the difference is 6782998696 which is 6 billion 782 million 998
thousand 696.
Example : The population of a state in 1995 was 94538469 and increased to
110500301 in 2002. Find the increase in population of the state in 2002
over that in 1995.
Solution : Population in 2002 = 1 1 0 5 0 0 3 0 1
Population in 1995 = – 9 4 5 3 8 4 6 9
1 5 9 6 1 8 3 2
Thus, in 2002, the population of the state increased by 15961832.
