Explained it better than any professor I've ever had, I'm looking at this for an Algorithms and Data Structures exam hehe

To simply say this, they used Euclid's Division Lemma over Modular Arithmetic to make it easier for negative integers as well. (a congruent to b (mod n)) Euclid's Division Lemma: If a ÷ n leaves a reminder b, and quotient q, then, a = nq + b where 0

Thank you! searched youtube looking for a clear explanation of finding the modulus with negative numbers and found exactly what I was looking for. Cheers!

This is nothing but a great explanation!

Thank you! It saved me a lot of time.

Thank you! I spent ALL morning trying to figure out how the R language was coming up with the modulus for negative numbers. Now I know how. Certainty I cannot let a computer language just calculate without knowing exactly what it is doing.

Holy moly!!! Niceuuu

@mr.stephengaming108 Год назад

Very clear explanation 😃😃

@Odarnoyeboah 7 месяцев назад

I have been looking for this long time ago but they gave me bullshit except urs thank you 💕

@Analytical_Mind 2 года назад

very well explained

@swaminathbera6407 Год назад

Add r to your number n, n = r + n such that it is divisible by divisor, that -r is your answer

@PPSVietnamTroly 3 месяца назад

Cool. But what is the application of the modulo with a negative?

@sababatamanna9226 2 года назад

Thanks!

@Forever._.curious.. 2 года назад

Thanx✨

hello sir sir it is quit difficult to understand that can this playlist is.cover full discreat mathematics which comes in gate exam PLZZ repaly me if possible Thank U sir ?!

How to read [-3]5 in the last video?

@razaacademy512 Год назад

sir which type of equip you are using for your presentation (mac book or ipad )

@ecengclub7196 Год назад

fyi every programming language have different implementation modulus just be aware when dealing with negative number

@onehornstudio7152 2 года назад

the formula doesn't work on -5 mod 5

@twilight7457 2 года назад

You don't need a formula in this case, it is just zero, since the remainder is zero.

@dineshmathsclasses2514 Год назад

Will -5 mod5 be 5 ?

@idealspeaker1377 Год назад

exactly.... the formula only works when the divisor and dividend are different and the dividend is a negative no.

@jaya71729 4 месяца назад

@galibmahim9544 Год назад

Well, I wonder what will be the answer to ( a mod - b) and ( - a mod - b )? If anyone knows , then please answer

@bongamusatsabedze5906 Год назад

The remainder you get when you divide "a by (-b)" is the same as the one you get when you divide "(-a) by b." Therefore ( a mod -b ) = (-a mod b)

@bongamusatsabedze5906 Год назад

( - a mod - b ) = (a mod b)

6 mod -5 how to calculate

@twilight7457 2 года назад

6 mod -5 = -6 mod 5.

@lordblanck7923 2 года назад

tf...its just plain idiotic....especially the shortcut method....the steps are badly explained...i am pretty sure its not supposed to be hard. i like the series but its just making things hard for people studying it,

@rk-iw1in 2 года назад

Glad to see I'm not the only one, took me half an hour to make sense of the whole thing.. doesn't happen in most videos though..

@gamenation7072 3 года назад

why are you so slow? you should complete one course first, please complete discrete math course first of all. otherwise, it won't help most of us

@monicabattacharya6416 3 года назад

hi sir ☺ Please start teaching FULL STACK DEVELOPMENT COURSE. I am learning now 😌. if you start it now , it will be helpful for many students who are preparing for placements.
