I would like to combine 2 INTs into one, but I do not want the sum, I what them placed next to each other. So if the first number is 4 and the second number is 8, I would like to combine them to one INT that would be 48.

Is there a way to write this mathematically? I guessed something like “DesiredNumber = (Number[1]&Number[2])” but of cause my guess was fail.

Well, assuming you're using a decimal system, you can always just use the way decimal works-

total = (number1 * 10) + number2

You then work backwards from the total number of things.

int ConatenateIntegers(int[] numbers)
{
int multiplier = 1;
int total = 0;
for(int i = numbers.Length - 1, i >= 0, i--)
{
total += (numbers _* multiplier)_
_multiplier = multiplier * 10;_
*}*
*}*
*```*
*<p>I think that'd do it? Check my maths.</p>*
