To calculate reminder on dividing the number by 7 11 and 13

Maths Tricks , short cut tricks for maths to make calculation easy and fast

To calculate reminder on dividing the number by 7 11 and 13 Let me explain this rule by taking examples consider number 34568276, we have to calculate the reminder on diving this number by 7 11 and 13 respectively. make triplets as written below starting from units place 34.........568..........276 now alternate sum = 34+276 = 310 and 568 and difference of these sums = 568-310 = 258 divide it by 7 we get reminder as 6 divide it by 11 we get reminder as 5 divide it by 13 we get reminder as 11: Example.
other examples:-
consider the number 4523895099854
triplet pairs are 4...523...895...099...854
alternate sums are 4+895+854=1753 and 523+099=622
difference = 1131
revise the same tripling process
1......131
so difference = 131-1 = 130
divide it by 7 we get reminder as 4
divide it by 11 we get reminder as 9
divide it by 13 we get reminder as 0; Is this maths trick helpful? (4907) (1932) Post / Read comment (15)

this is complete rubbish
34568276/7 will give remainder as 1
34568276/11 will give remainder as 4
34568276/13 will give remainder as 2

:D
now alternate sum = 34+276 = 310 and 568
and difference of these sums = 310-568=(-258)
Now, continue...
If final answer (remainder) is in minus, add divisor with the result.
