@Melody Im so sorry that I forgot to include that 8+2=10 my mistake :(. Okay, I will try to answer your questions.

Question 1: So in 1 hour, 2+4+6=12

Question 2: So in 24 hours, it will be (2+4+6)12=144

Question 3: That would be 1+2+3+4...+11+12=(1+12)12/2=78 extra

Question 4: I think that would be just 78*2=156 extra in 24 hours.

Question 5: 144+156=300 chimes in 24 hours?

Please Tell me my errors if I have any. THANK YOU MELODY!
