Who said anything about deleting any numbers? The code fragment I posted did not delete any numbers; it merely made a new array with everything that was not #+. In the original post there were no strings. (By the way, you wrote "trailing" where you meant "leading".) On Mon, 3 Dec 2018 at 08:40,

Thinking about this functionally, you want to sum the array elements that are not + . So, (array select: [:each | each ~~ #+]) sum The *best* approach is not to put the + symbols into the array in the first place. On Sun, 2 Dec 2018 at 23:46, Roelof Wobben wrote: > Op 2-12-2018 om 11:15

Hi Roelof, Two problems: 1. + is a symbol so compare it to #+ 2. A false case is needed to return the untouched sum, otherwise it truns to nil #(+1 -8) inject: 0 into: [:sum :each | each ~= #+ ifTrue: [sum +  each] ifFalse: [sum]] . Hilaire -- Dr. Geo http://drgeo.eu
