A family member was asking me for math help out the blue, and Im pretty sure this is for her HS kid. I actually never encountered this when I was in grade school so I looked it up and it's just such an unnecessary way of presenting numbers (and even more redundant based on the basic mathematical equations I've seen)

This what happens for letting commom core go unchecked

I wish my math classes had this. S*** is easy af. Divide the number by the modular number and the number is then equal to the remainder.

This is actually very useful in certain applications

Bro what is this nonsense?

it's just calculating the remainder lmfao why make it so complicated

What’s the point of anybody knowing math if they’re gonna keep changing it

Hated math

It’s very useful for simple algorithms, for example if you want to determine whether a number is even or oneven. It’s also used in more complex algorithms— very much in the field of cryptography. The reason why you are able to browse KTT2 securely with HTTPS even involves modular arithmetic during client-server key exchange (Diffie-Hellman).
It’s not dumb, you just haven’t explored the application yet.

Its easy I promise you

f*** all maths

Modular arithmetic is the reason you can put sensitive data on the internet without people stealing it (credit card numbers, d*** pictures, etc)

It is very important

It doesn’t change this is just a different method of doing the same thing

Its important af in computer science

the more visual explanation could help some people understand

You lost

Maths? You bri’ish now?

Whoa, I've never seen this s*** at all in my life. Where would this apply then?

nah just wanna emphasize that I mean all of them

"modular arithmetic is one of the foundations of number theory, touching on almost every aspect of its study, and it is also used extensively in group theory, ring theory, knot theory, and abstract algebra. In applied mathematics, it is used in computer algebra, cryptography, computer science, chemistry and the visual and musical arts."

Never coded in my life, so this is probably why

you might be familiar with this use of it:

"A familiar use of modular arithmetic is in the 12-hour clock, in which the day is divided into two 12-hour periods. If the time is 7:00 now, then 8 hours later it will be 3:00"
