Why is division a different function than modulus? Do they not preform the same function?

Answer 1

Because division / show the Quotient and the % shows us reminder.
Ex. 2/2 = 1
2%2=0
It shows different values That's why we can not use same function. I hope you understand.

Answer 2

If I have 7 cookies and 2 kids, how many complete cookies will each kid get?

7/2 == 3

(Decimals are ignored.)

And how many cookies will be left over?

7%2 == 1

Answer 3

Modulus is for Remainder,
Division is for, Division.

Answer 4

Why?
This function is very useful for mathematical calculations. For example, a decimal number can be converted into a binary number using the modulo division. This is a good task for code practice in any program language. I recommend solving that.

Answer 5

Their roles are different. One gives remainder while the other gives quotient of division.
