transposition - (mathematics) the transfer of a quantity form one side of an equation to the other along with a change of sign

number crunching - performing complex and lengthy numerical calculations

mathematical operation, mathematical process, operation - (mathematics) calculation by mathematical methods; "the problems at the end of the chapter demonstrated the mathematical processes involved in the derivation"; "they were learning the basic operations of arithmetic"

recalculation - the act of calculating again (usually to eliminate errors or to include additional data); "recalculation yielded a much larger value"

procedure, process - a particular course of action intended to achieve a result; "the procedure of obtaining a driver's license"; "it was a process of trial and error"

problem solving - the thought processes involved in solving a problem

extrapolation - (mathematics) calculation of the value of a function outside the range of known values

interpolation - (mathematics) calculation of the value of a function between the values already known

conversion - a change in the units or form of an expression: "conversion from Fahrenheit to Centigrade"

approximation, estimate, estimation, idea - an approximate calculation of quantity or degree or worth; "an estimate of what it would cost"; "a rough idea how long it would take"
