Hi, All

Is there a way to use multiple variables in pure function with map.

What I want to do is like this:

ab = {{1, 2}, {2, 3}, {3, 4}};
(#[[1]] + #[[2]]) & /@ ab
{3, 5, 7}

Instead of refer to elements in list I want to use multiple variables
in pure function.

something like this:
ab = {{1, 2}, {2, 3}, {3, 4}};
(#1 + #2) & /@ ab
To do the same thing as the above example.

Best
