Dr. UV's Walking Weaves

Walking and weaving. Every mailbox on the route became a puzzle — thirty of them, made between three and seven in the evening, and on this site the same night.

✦ HOW TO WEAVE A MAILBOX
The mailbox number is the board. In a Double Weave it sits on both sides of the equals sign, with the digits in the same order. Each side gets its own hand of symbols and may use only those. Make both sides equal the same number — that is the answer.
Free moves: brackets, joining digits (1 and 6 make 16), using a board digit as an exponent, side-by-side multiply, and stacked roots (√√ is a fourth root). 0! = 1.
Weave It lets you rearrange the digits. Just Weave It uses no symbols at all. Vinkit™ uses a vinculum bar.
Worked example — mailbox 154
Left hand √ × +, right hand × − √.
154 = 154 becomes 1 × √(5 + 4) = 1 × (5 − √4) = 3. The same root does two jobs: it covers the whole sum on the left and only the 4 on the right.
