'accurately-computed' originates from the combination of 'accurate' and 'compute'. 'Accurate' comes from Latin 'accuratus', meaning 'done with care', and 'compute' comes from Latin 'computare', meaning 'to reckon together'.

'Accurate' evolved from the Latin 'accuratus' through Middle English, while 'compute' evolved from the Latin 'computare' through Old French 'computer'.

Initially, 'accurate' meant 'done with care', and 'compute' meant 'to reckon together'. Over time, they combined to mean 'calculated with precision'.
