CO OZNACZA SŁOWO MENTAL ARITHMETIC
Obliczenia psychiczne
Obliczenia psychiczne obejmują obliczenia arytmetyczne przy użyciu tylko ludzkiego mózgu, bez pomocy kalkulatorów, komputerów, pióra i papieru. Ludzie używają obliczania umysłowego, gdy narzędzia obliczeniowe nie są dostępne, gdy są szybsze niż inne sposoby obliczania lub w kontekście konkurencji. Kalkulacja mentalna często polega na wykorzystaniu specyficznych technik opracowanych dla konkretnych problemów. Wiele z tych technik wykorzystuje lub polega na systemie dziesiętnych liczb. Zwykle wybór radix decyduje o metodach, a także jakie obliczenia są łatwiejsze do wykonania psychicznie. Na przykład pomnożenie lub dzielenie się o dziesięć jest łatwym zadaniem podczas pracy w liczbie dziesiętnej, podczas gdy mnożenie lub dzielenie przez szesnaście nie jest; jest jednak prawdą, gdy działa w szesnastkowych.
