In my native language we have clearly defined and official terms for the operands involved in mathematical calculations. I am talking about the basic four arithmetic operations addition, subtraction, multiplication and division.
I know some of the terms but am unable to find equivalent translations into English for them all. For example, when performing addition, the stuff being added is called "addend" and the result "sum" in Danish:
addend + addend = sum
In English I realize that we have the word "sum" but I can't in my dictionary nor on Wikipedia find the English equivalent of "addend". Same goes for the other three operations.
In Danish:
addend + addend = sum
minuend - subtrahend = forskel
faktor or multiplikand × faktor or multiplikator = produkt
dividend / divisor = kvotient
In English:
_____ + _____ = sum
_____ - _____ = difference
factor × factor = product
_____ / divisor = fraction or quotient
I would appreciate help with filling out these empty spots of my English knowledge with the formal and correct terminology.
