1 p.m. (13.00) because then it will be 11 a.m. add 2 hrs
add 2 hr and 11 hrs and get get 1 o'clock
you can add Mod 12, this is like clock math. If it is 11 o'clock and you add 2 hours, it is then 1 o'clock. This is called addition Mod 12.
add -10... 11 + (-10) = 11-10=1 ur welcome! So that would be 2x + 11 = 1 where x = -5.
because if you add 1 to 12 you will get one more not less.

To get from 2 to 5 you are multliplying 2 by 2 and adding 1. The difference is 3. Now, to get from 5 to 11 you do the same thing - multipy 5 by 2 and add 1 to get 11. That's what you do to 23. Multlipy by 2 and add 1 to get 47.
2/15 + 1 + 7/10 = 11/6
At least 11 of them.
48
11/15
1,2, 11, 22 The pairs are 1 & 22, 2&11 :)
