A calculating machine is a machine designed to come up with calculations (i.e. computations); the most famous is probably the VictorianBritish scientist Charles Babbage's Difference Engine (No. 2), designed in the 1840s but never completed in the inventor's lifetime*.

U.S. Patent 388116 — Calculating machine — W. S. Burroughs
A calculatingmachine is thus a device for calculation, which supports the computation of mathematical tasks, as as little as possible cognitive expenditure is demanded from the user of the machine.
That means that the calculation 9+1 is to be mastered simply, however 9999+1 high energy expenditure required and probably to blocking the machine led.
This may be justified in it that the calculatingmachines at the beginning of their development stood, consequently for practical application yet not developed enough and too expensively in the production was.
Que si tu veux, outre la facilité du mouvement de l'opération, savoir quelle est la facilité de l'opération même, c'est-à-dire la facilité qu'il y a en l'opération par cette machine, tu le peux, si tu prends la peine de la comparer avec les méthodes d'opérer par le jeton et par la plume.
Tu sais de même comme, en opérant par la plume, on est à tous les moments obligé de retenir ou d'emprunter les nombres nécessaires, et combien d'erreurs se glissent dans ces rétentions et emprunts à moins d'une très longue habitude et en outre d'une attention profonde et qui fatigue l'esprit en peu de temps.
Cette machine délivre celui qui opère par elle de cette vexation ; il suffit qu'il ait le jugement, elle le relève du défaut de la mémoire ; et, sans rien retenir ni emprunter, elle fait d'elle-même ce qu'il désire, sans même qu'il y pense.
