"Math"
Solution
This is a Strands, a type of puzzle most associated with the daily NYT strands.
The objective is to form words using paths through the letters, and eventually to use each letter once. There is one Spangram that touches opposite sides of the grid, which is used in the meta of this round.
Unlike standard Strands puzzles, this puzzle contains non-letter characters. Each "word" is instead a famous equation. Most letters fit their appropriate capitalization, except the names of functions such as "MOD" and "LN".
