how to calculate MOD?

Question

G = E OR D AND A + 8 <= B^2 MOD C
G = false OR true AND 6 + 8 <= 9^2 MOD 4

G = false OR true AND 6 + 8 <= 81 MOD 4

G = false OR true AND 6 + 8 <= 1

G = false OR true AND 14 <= 1

G = false OR true AND false

G = true AND false

G = false


how do u get 1 after having G = false OR true AND 6 + 8 <= 81 MOD 4


81 MOD 4 =????

Answer 1

mod is simply remainder
81/4= 20 remainder 1
mod or % gives out remainder
hence 1

Answer 2

MOD is short for modulo, it means the same thing as remainder.

81 mod 4 = 1

To calculate M = I mod J in a programming language that has no modulo function:

Integer I, J, K, M

K = I/J ## integer truncation assumed #
M = I - (K*J)
