Correct! For every 50 years, rates go down by 0.5%.

Why isn't bumping allowed here?

Well, the Scratch Forums has it, and it's kind of like FluxBB too (Scratch Forums is DjangoBB). Anyways, rules are rules. No bumping. sad

Hola:

Okay, regarding #1:

Hindi ako sang-ayon diyan. I disagree with that.

And also, what if some Filipino (or whoever nationality) posted a topic, and has titles like "Tulong!" "Hola!" "Bonjour!" "Hola! Yo soy mathaholic."?

Regarding #1+1:

Hmm... Well, in Scratch, they can create multiple accounts... but, I am neutral with that.

Regarding #5:

Well, I have explained that in this forum, but anyways, since the bump is not that popular yet in this forum...

Regarding #6:

I am neutral with that.

Regarding #9:

See #6.

Regarding #2^4:

Okay, what if we have a first grader here, and asks "Can you help me?" and asks what is 82+19? Or 51*4? 97-37? 360/6? A shape with 6 sides?
And besides, we should be kind. smile

Regarding #18:

What if I discovered that (2^57,885,161)-1 is not a prime at all? tongue
Or, 1+1 is 1? lol
Or there are only a limited amount of primes?
Or maybe pi is 3.15169275493209283827412039829847938274238129740938192298742312329 (I just randomly put those digits)?

All in all, I'm sorry for raging. Just explaining what could happen. Kapayapaan (Peace)!

Whoops, I forgot to specify:

#91. Does the sum of the digits of the answer in #90 prime?

#413 Re: Puzzles and Games » Cube it! » 2014-05-28 12:38:18

166375 equals 55 cubed equals 11 cubed times 5 cubed equals 1331 times 125

#414 Re: Puzzles and Games » Prime Number Challenges » 2014-05-28 12:35:02

Hmm, since I'm too lazy to check...

#90. What is the square root of 121?

#91. It's obvious that it's prime. But, does the sum of its digits equal a prime number, too?

#416 Re: Puzzles and Games » Cube it! » 2014-05-27 22:29:17

148877 equals 53 cubed equals 380^2+66^2+11^2 equals 144400+4356+121 equals 2809 times 53

The population per day is going down.

Yup, that's what other censuses did, so I decided to do so too. tongue
