Lotus 1-2-3 had a Solver (two actually, one called "Solver" and one called "What-If") in 1989. Yes, LibreOffice has one too. Does Microsoft tell their custome

Lotus 1-2-3 had a Solver (two actually, one called "Solver" and one called "What-If") in 1989. Yes, LibreOffice has one too. Does Microsoft tell their customers they invented these features? Just a few days ago I saw a Windows developer who thought Microsoft invented conditional breakpoints.
