Ah, those dollar signs... *Relative* is like my pot's clay, it shifts when you move it. *Absolute*, with dollar signs both sides like `$A$1`, is fixed, like my stubborn arthritis. *Mixed* is one side fixed, like `A$1`, chigem, just like how I can only teach the rim technique one specific way now. I memorized it all for the government reports, but my hands, they learned by doing—the sheet never tells you which one you really need.
