hi @N4i9kita when numbers are really big, you can either use some other language (both java and python are good with big int) or if you want to work in c++ you will have to store numbers in an array and perform operations on that array. Store each number as a separate element of the array, for eg if your number is 120 then you will have to store it as {1, 2, 0}
