Gosh, the examples here.
/ is for division.
% is for modulus.
5/3 == 1 with remainder 2
5%3 is 2 (It returns the remainder of 5/3)
Likewise,
4/3 == 1 with remainder 1
4%3 is 1 (Because remainder of 4/3 is 1)
As simple as that.

Hi Dia :)
"/" is for division
"%" is for modulus
-------------------------------------------------------------
Example of DIVISION:
6/3 = 2
This would return 2 due to the fact that 3 goes into 6 twice. In other words, it gives you the quotient.
-------------------------------------------------------------
Example #1 of MODULUS:
10%3 = 1
Modulus gives the remainder of the division of one number by another.
It's like you were doing a regular division (10/3) but you don't care about the quotient of that division (3), instead, you want the remainder (1)
So, in this example the modulus would return 1 due to the fact that 3 goes into 10 three times and then gives the 1 that is left over.
------------------------------------------------------------
Example #2 of MODULUS:
What if you reverse the previous statement?
3%10 = 3
Here's how to solve it:
- Step 1: Find the quotient 3/10 = 0.3
- Step 2:
Take the left side of the decimal. So we take 0 from 0.3 (this is what the "floor" function does)
- Step 3:
Multiply that 0 by 10 (the denominator)
0*10 = 0
- Step 4:
Subtract 0 (the result) from 3 (the numerator)
3 - 0 = 3
That's it đ
------------------------------------------------------------
You might find this formula useful for MODULUS:
a%b = a - floor(a/b)*b
Application of the formula:
3%10 = 3 - floor(3/10)*10
3%10 = 3 - floor(0.3)*10
3%10 = 3 - 0*10
3%10 = 3 - 0
3%10 = 3
Hope this helps you đ

@Dia, it means that
how many times 1 comes in the table of 3, ans is 0.
1/3=0 and 1%3=1
how many times 2 comes in table of 3, 0 time
2/3=0 and 2%3=2
how many times 3 comes in table of 3, 1 time
3/3=1 and 3%3=0
how many times 4 comes in table of 3, 1 time
4/3=1 and 4%3=1
how many times 5 comes in table of 3, 1 time with remainder of 2,
5/3=1 and 5%3=2

/ is division operator, outputs the quotient of calculation, eg. 5/2=2
while % is modulo operator, outputs the remainder of calculation, eg. 5%2=1

+ 4

"/ "is simple division so d output is the quotient
ie 6/2 =3//its just lik division
"%" tells the remainder after division
ie 7%2=1
**hope this helps

i really dont understand about 0*3+1
where 0 come from?

+ 2

ooo now i understood now thank for the explanation

+ 1

/ is division. % gives you the rest.
1%3=1 because 1=0*3+1
2%3 = 2 because 2=0*3+2
3%3=0 because 3=1*3+0
4%3 = 1 because 4=1*3+1

+ 1

thank you, but i still don't understand about "1%3=1 because 1=0*3+2" where 0 come from?

How often does 3 fit into 1? Zero times. What do you have to add still? One.
It's division with remainder. Fourth grade. Before you learn about fractions.

it's very hard to understand about % and/ please example more detail about it.

thanks about information

thank you all for the material

may i ask why 3/10=0.3 why not 3
