Solving an equation means finding which values of its unknowns make the statement true, and the equals sign itself was invented only in 1557, well after equations had been written and solved for centuries using prose and other notations.

equations as mathematical statements, solved in prose and other notations, are centuries older, as the description notes.EquationFilter Results8 entriesBranchAllAlgebraic Topology (3)Differential
