Commutation and What This Means for Subtraction

Look at how standard theory handles parentheses in subtraction:

9 – 3 + 5 becomes 9 – (3 + 5) …

but the answers don’t match:

Mainstream math labels subtraction as “broken” here and gives up on the associative property. But what if the math isn’t broken—just the way we write it down?

In Chapter 3, I expose why traditional associative rules fail subtraction and demonstrate how a single, logical principle—the invisible primary addition operator—restores 100% consistency to grouping subtraction problems.
