## Solve Path

The general premise involves deducing which colors and shapes refer to which operations and numbers. A good break-in is expressions that equal 12, as there are multiple expressions with some only using one operation. Below are some strategies that can be applied.

• Bounding arguments can be used to narrow down possible operations. For example, since 12 can be written as the product of at most three distinct whole number, the color red must represent multiplication.
• Tracking possible numbers can be used if one knows that a number must appear in that equation. For example, after finding that green is multiplication, the number 1 must be represented by either the triangle, square, or pentagon.
• After narrowing down some values, writing a computer program that assumes a color as an operation can be done to brute force possibilities.

Once all the symbols and numbers are found, the rest of the expressions can be calculated, and the answer can be extracted via A1Z26.
