Squares with number 5 at the unit place:

Ex:....

We know 5² = 25
So for numbers like :
15² = 225
Explanation : 5² is 25 and what comes after 1 is 2 so multiplying 1 and 2 we get 2 hence the result 225
.
.
.
Few more
25² = 5² is 25 and 3 comes after 2 so 3×2 is 6 = 625

35² = 5² is 25 and 4 comes after 3 so 4×3 is 12 = 1225

45² = 5² is 25 and 5 comes after 4 so 5×4 is 6 = 2025
Upto 95 you could go on but the calculation gets difficult as you progress further

One trick is also to substract last digit to remaining digit and keep doing it till you get answer. Like 341 is divisible by 11 as 34-1 is 33 which is divisible by 11.

Thank you so much I needed this for my math 😄😄😄

Um I tried it and 1232 dosen't work... Did I do something wrong i divided it by 11 and it is evenly divisible.

[Hello__Bye]

Thank bro for this as tomorrow is my exam

I have a reason
981
9-8=*1*
*1*+1=2
The Result is the Remainder so
981 ÷ 11 has a remainder of 2
If the result is 12 or more subtract the number by divisible of 11

If the result is 25, subtract 25 from the largest number that is divisible by 11 (22) 25-22=3
The remainder is 3

This doesn't work if the difference is a negative
245
2-4= (-2) <- a negative number so it doesn't work, even though you add 5 and became a positive it doesn't work as well

Ima grade 5 student and this is the best trick for me

[Inspire_before_expire]

i tried this in another number i do like this but thats wrong
in your numbers there is no zero

[inesjasserand]

but if the number is smaller than the number next to it what shall we do?

[PraveenKumar-mpfw]

can you apply this method to 1232523121.. by this method I'm getting wrong answer..

[Deenivibzz]

Yes, sir I love you're explanation reply me

[matiaspereira]

Another trick is substracting the last digit by the rest of the number

[mariahvlogs]

how come at 1:25, the answer is 2?
1: 1-5=4
2: 4+2=6
3: 6-3=3
4: 3+7=10


please help me I don't understand

[NARZARY]

6__261 if the both was missing and shown like this how to divide by 11 the please explain

[barryjackson]

There are 2 other ways to test A number for divisibility by 11.

[lucheeket]

Only told that 0 other than 11 is also alright prior to the end. Obviously 121 and 132 gives zero. Read until the end shall do.
