Today we are going to learn How to multiply repeated numbers in seconds and save more time for solving other questions in banking exams.

Lets take any of number from 1 to 9

88888*555

11111*8 and 555*111 will be same as 88888*555

lets make very easy for multiply'

11111*111*8*5

1233321*40

Multiply 1*0 and  all digits in reverse form by 4.

1*0=0

1*4=4
2*4=8
3*4=(1)2 carry forward one to next
3*4=12+(1)=(1)3 carry forward one to next
3*4=12+(1)=(1)3
2*4=8+(1)=9
1*4=4

Ans=49332840


Example 2.

555*999

111*5*111*9
111*111*9*5
12321*45

1*5=5
1*4+2*5=14
2*4+3*5=23+1=24
3*4+2*5=22+2=24
2*4+1*5=13+2=15
1*4=4+1=5

Ans 554445
