Solving the Stellar Blade Wisdom Puzzle is arguably tougher than the Simple Puzzle before it, with yet more vague math stuff to do to get a four-digit passcode. it works just like the previous puzzle in that you need to grab it from the Bulletin Board, submit the passcode into the same keypad, then return to the board for your rewards.

The big difference is that figuring out the solution is a lot harder, requiring you to square the numbers, though that really isn't clear when looking at 37#21 and the other clues. To help you get through this math puzzle quickly, I've explained the answer to the Wisdom Puzzle in Stellar Blade with my working so you can see how the answer is derived from the baffling sequence of numbers.

How to solve the Wisdom Puzzle in Stellar Blade

The answer to the Stellar Blade Wisdom Puzzle is 5005, and I'd say this puzzle is definitely harder than the previous one, even though there are arguably fewer steps to it. The Wisdom Puzzle goes as follows:

37#21 = 928

77#44 = 3993

123#17 = 14840

71#6 = ?

The pattern here is that you square both numbers (multiplying them by themselves), and then subtract the second number from the first. This can be expressed in the formula (x*x)-(y*y). So, in the first line of the pattern, they multiply 37 by 37 for 1369, and then they multiply 21 by 21 to get 441. Then you get the answer by subtracting 441 from 1369, which is 928!

Apply this pattern to the final row, and you get the answer: 71 times 71 is 5041, and 6 times 6 is 36. Then you take 36 from 5041 to get 5005, the answer!

Enter it into the same console as the Stellar Blade simple puzzle before, and then head back to the Bulletin Board to get another 1000 Gold and the Queen of Arithmetic Badge.
