Anwer to challenge question 6 234*111=???
unit digit : 4(same digit)
digit in ten’s place : 3+4=7
digit in hudredth’s place: 2+3+4=9
digit in Thousanth’s place: 2+3=5
digit in ten-thousandth’s place : 2
so answer will be 25973.If there is any carry over,we have to add them .
we can do it from left to right also.Don”t forget to add the carry overs.
so in general, if pqr is a 3 digit number.
So we need to find pqr*111=?
ans will be:
p (p+q) (p+q+r) (q+r) r (taking into consideration the carry overs).
similarly, 854*111 =94794(in this case ,we have carry overs,we need to take those into account).
