Given
(−414×−916)mod12=Y
Identify which one of the following options does NOT give an equivalent expression to that above ?
0
(6+8)mod12
48 mod 12
14 mod 12
I expanded the brackets so
1) -414 * -916 = 379224
379224/12 = 31602
31602 x 12 +0
A = 0 x 12 + 0 (?) I thought it wasnt this answer cos there was no mod in it...
B (6+8) mod 12
= 14/12 = 1 x 12 +2
C 48 mod 12 = 4 x 12 +0
D 14 mod 12 = 1 x 12 +2
1) I am confused as to the difference between B and D
D is stated as the right answer...but I am unsure why
HINT: $$(-414)\cdot(-916)=379224=12\cdot 31602$$
