Where can I find 991ms mods?
That’s simple,
- Divide the two numbers ( eg. 7/3 = 2.333333)
- eliminate the decimal part (i.e., make the 2.33333 → 2) ( If there is no decimal part, the MOD value is 0, eg.
- multiply the divisor with the number you just found out ( 3 * 2 = 6)
- now subtract the result from the dividend (7 – 6 = 1, which is your MOD value)
What is the meaning of 1 mod 3?
Answer: 1 mod 3 is 1.
Let’s find 1 mod 3. Explanation: 1 mod 3 equals 1, since 1/3 = 0 with a remainder of 1. To find 1 mod 3 using the modulus method, we first find the highest multiple of the divisor, 3 that is equal to or less than the dividend, 1.
