what does mod4 mean ?

Question

what does module 4 mean in maths?

Answer 1

mod is the function which is used to give out the remainder.
example when 11/4 gives mod as 3
hence mod 4 means when one number is divided by the other it gives the remainder as 4.

Answer 2

It means to divide a number by 4 as many times as possible and the remainder will be the number mod4.
For example 4 (mod 4) = 0 because 4/4 = 1 with no remainder.
5 (mod 4) = 1 because 5/4 = 1 with remainder 1
6 (mod 4) = 2 because 6/4 = 1 with remainder 2
7 (mod 4) =3 B=because 7/4 = 1 with remainder 3
8 (mod 4) = 0 because 8/4 = 2 with remainder 0
9 (mod 4 ) = 1 because 9/4 = 2 with remainder 1
So just divide the given number by 4 and thr remainder is the answer.

Answer 3

Divide by four and what is the remainder.

7 mod 4 will give you 3. 21 mod 4 is 1. 12 mod 4 is 0.

The only four numbers there are in mod 4 are: 0, 1, 2, and 3.

Answer 4

a modulo n (abbreviated as a mod n) is the remainder, on division of a by n.

So a mod4 is the remainder, on division of a by 4.
For case of set of numbers A, A mod4 is theset of numbers that are remainders of numbers in A devided by 4.

I hope this helps you.

Answer 5

xmody:when u divide x by y u have x=yk+u where k=0,1,2,3....
u=xmody.
if x=ky then xmody=0
if x=ky+1 then xmody=1 etc...
xmod4 is when u divide x by 4.
