Just pass a function to the sort, based on which you want to sort the array

.sort((a,b) => b - a)

Your code

this.display=this.addition.sort();

will sort the array in ascending order, to sort in descending order you need to pass a comparator function.

this.display=this.addition.sort((a,b) => b - a);
