Question

Find the additive inverse of -9 on the 12-hour clock

Answer 1

-9 on the 12 hour clock is more like 3'o clock, right?

Answer 2

\[3 + x = 12 \]Because 12 is equivalent to 0, you must solve this equation.

Answer 3

Or am I going wrong?

Answer 4

if 0 is the identity it will be 9 right?

Answer 5

Yes.

Answer 6

But, careful, it's the 12-hour clock.

Answer 7

This is just a coincidence that we have the additive inverses same.
