Question

a=(3,[-2]), calculate the modulus of a, to 1 decimal place.​

Answer 1

Answer:

Modular arithmetic is sometimes called clock arithmetic, since analog clocks wrap around times past 12, meaning they work on a modulus of 12. If the hour hand of a clock currently points to 8, then in 5 hours it will point to 1. While 8 + 5 = 13, the clock wraps around after 12, so all times can be thought of as modulus 12. Mathematically, 13 mod 12 = 1.
