|"The calculator that thinks only if you think, too," QAMA requires the operator to first enter a reasonable estimate. QAMA encourages rounding and rapid back-of-the-envelope reckoning, but does not tolerate errors of magnitude or sign, or of basic operations with single digits. Read user instructions, scope, and more. QAMA derives from "Quick Approximate Mental Arithmetic," but also happens to mean “How Much?" in Hebrew.|
