English term

distributed across the list

English Tech/Engineering Mathematics & Statistics calculator
talking about operations with lists of numbers

"Addition, subtraction, multiplication, division
Multiplication and division of a list by a single number is distributed across the list"

... what does it mean? I think that the single number should be multiplied by each number in the list, or...??

thanks!

Each member of the list is to be multiplied/added/etc.

Your understanding of the term is correct.

It means each element of the list is to be multiplied/divided/etc., by the single number.

Eg., a*(b+c+d) = a*b + a*c + a*d

This is the familiar distributive law of algebra. The same is meant in the list operation you have mentioned.

Thank you.
agree Attila Piróth : http://mathworld.wolfram.com/Distributive.html. (However "list" does not sound like the best choice of word.)

Thank you. List is a special type of data structure used in Artificial Intelligence and Computer Science.
neutral Richard Benham : Hmmm. I am worried by your example, which shows a sum rather than a list....
