Question
What is the result of (123*(-10))mod 19
Solution
The result of (123*(-10))mod 19 can be calculated as follows:
Step 1: Multiply 123 by -10 to get -1230.
Step 2: Find the modulus of -1230 and 19. The modulus is the remainder after division.
-1230 mod 19 = -4
However, in modular arithmetic, we usually want a positive result. We can get this by adding the modulus (19) to the result:
-4 + 19 = 15
So, (123*(-10))mod 19 = 15.
