What is 9 mod 22?

How to compute 9 mod 22?

The simplest approach is to use the "mod" operator (often denoted as "%" in many programming languages), but you could do it manually in the following way:

$\mathrm{Remainder}=N-(M\times \lfloor \frac{N}{M}\rfloor )$

(where N is the dividend, M is the divisor and $\lfloor \frac{N}{M}\rfloor$ represents the integer part of the quotient)

1. 9 / 22 = 0.40909090909091
2. ⌊0.40909090909091⌋ = 0 (We only keep the integer part)
3. 22 × 0 = 0
4. 9 - 0 = 9 (Subtracting gives us the remainder)

In short: 9 − (22 × ⌊9 / 22⌋) = 9

Is 9 divisible by 22?

A number is said to be divisible by another number, if the remainder of the division is zero.

Given that the result of 9 mod 22 is 9, this indicates that dividing 9 by 22 leaves a remainder of 9. Therefore, no, since the remainder isn't zero, 9 is not divisible by 22.
