Mod

[RN1]

79 Mod 92 evaluates to 79

156 Mod 249 evaluates to 156

So while using the Mod operator, if the first number is less than the
second number, will the result be ALWAYS EQUAL to the first number?

Yes. Think back to second or third grade when learning about division.
If you divide 79 by 92, you got a remainder, right? 92 gazinto 79 zero
times with a remainder of 79.
That's the modulus, or mod for short.

Not exactly -390 is less than 79 but -390 mod 79 is 74.

Typo: -74

-19 Mod 7 evaluates to -5....that's fine but

-19 Mod -7 also evaluates to -5. Why? Shouldn't it evaluate to 5?

Also how does 19 Mod -7 evaluate to 5 (& not -5)?

-7 * 2 = -14

What do you have to add to -14 to get -19?

Also how does 19 Mod -7 evaluate to 5 (& not -5)?

Again, -7 * -2 = 14. What do you have to add to 14 to get 19?
