Question

Write the numeral in base ten 555six

Answer 1

I'll write it in expanded form for base 6 and you can take it from there.

555₆
=5*6² + 5*6¹ + 5*6⁰

Answer 2

555₆ = 5x6^2 + 5x6 + 5
= 215

Editorial: This topic was the big craze back in the 60's after "Sputnik" caused a frenzy of "New Math" to be introduced, and kids had to learn how to do arithmetic in different bases.
Unfortunately, that left less time for learning ordinary arithmetic like 56 ÷ 12
Fortunately, clearer heads prevailed and such topics were dropped for more relevant math.
The above topic only makes sense in the study of computer science, and then only base 2, base 8 or base 16.
Sorry about the rant.

Answer 3

I'll join the party and give mine!
Those who use American and Canadian currencies would be advantaged to convert to and from base 5, since change in those currencies work in a good part in base 5.

The penny being 1, the nickel being 5, and the quarter being 25, or 5². Forget about the dime (10 cents) for this purpose.

So 244₅ is simply the value of 2 quarters, 4 nickels and 4 pennies = 74₁₀.

Conversely, 108₁₀ would be 4 quarters, 1 nickel and 3 pennies, making 413₅.

Have fun!
