I remember base numbers are also like a way to oount, like, base ten would be 1 2 3 4 5 6 7 8 9 10, while base 2 would be like 2 4 6 8 10, or something. We learned it in fifth grade. And I just remembered I'm actually in 7th grade xD

Wait, base 2 wouldn't be 2 4 6 8 10...

It's hard o-o;;

base definition
base-A number that is multiplied by itself as many times as indicated by an exponent. definition by http://www.atis.org/tg2k/_base.html

But a base number is also a way to count, for example:

base numbers
In base four, each digit in a number represents the number of copies of that power of four. That is, the first digit tells you how many ones you have; the second tells you how many fours you have; the third tells you how many sixteens (four-times-fours) you have; the fourth tells you how many sixty-fours (four-times-four-times-fours) you have; and so on. The methodology for conversion between decimal and base-four numbers is just like that for decimals and binaries, except that binary digits can be only "0" or "1", while the digits for base-four numbers can be "0", "1", "2", or "3". (As you might expect, there is no single solitary digit in base-four math that represents the quantity "four".)

0.upto(9) do |m|
0.upto(9) do |e|
0.upto(9) do |p|
if(((p + e*5 + e*25 + m*125) + (p + e*7 + e*49 +m*343)) == (p + e*8 + e*64 + m*512))
puts m.to_s + e.to_s + e.to_s + p.to_s
end
end
end
end

it's a ruby program and the answers I got were 1332 and 2664 and 3996

I got 3 different answers they all work

But can there be 3 answers? what if there's only one number o-o;;

Do you think TNT would hint that there could be one number?

Wait, I just noticed something about your answer xD

1332 times 2 equals 2664

1332 times 3 equals 3996

I submitted 1332

I'm going to wait a few minutes. Maybe thirty seconds. Or maybe now xD

Does the program automatically check if it's correct?

Well it's wrong. I don't know what sort of calculator you used. =/

Darn it! You posted it was wrong right after I submitted it ;-;

It checks all palindromic 4 digit numbers and returns only the ones that are right

I also posted 1332, it should be right....maybe...

But does it check that if you multiply the base 5 by 1332 and 1332 by base 7 and 1332 by base 8? Because that's part of the question.

I've learned my lesson to be patient xD

How is it wrong?

The bases are hard coded

Ah, I see =)

Then it doesn't seem like you're wrong.
