Hi parents,


This question may be asked before but how do I teach my kid on long division with missing digit?

Example : 8_3 / 5 - 168 R3

How do i arrive at the answer for the blank?

Is that 8_3/5=168R3
168 is the quotient
3 is the remainder
168*5=840
840+3=843
so the answer is 4

Oh!! Thanks! Thanks! Another question, for P3 Level is it usually just to find 1 missing digit? Will the kid be tested on 2 missing digit instead of 1?

U r welcome!
Usually they asked the number.I think,P3 kid should be able to give the number.Asking missing digit is easier version.For the starting they asked like that then the difficulty go up.

Need help on the following question :


50 children were at a party.
Each boy ate 10 jelly beans while each girl ate 7 jelly beans.
All the girls ate 44 more jelly beans than all the boys.
How many boys and how many grls are at the party?

Other than Guess & Check method, which other method can we use to solve this?
