TLDR: In octal system, the weight of the digit in a position is an exponent of 8. So 31 = (3×8¹ + 1×8⁰) = (3×8 + 1×1) = 24 + 1 = 25.

Sure, it’s shorter, but is it really a summary of my comment, or just a more technical explanation?
My comment tries to teach via example, while theirs tries to teach using math. I chose my method because it’s the most accessible to people who aren’t math-inclined, but also because it takes the least cognitive effort to understand, which is an important quality for a social media comment to have nowadays.
Besides, you obviously don’t have to read the whole table (you already know how to count to 25). Just scan the right column to see what it’s doing differently.
