What is the greatest product obtainable from two integers whose sum is 24?
when you're trying to find the greatest product, you want to have two numbers that are the closest possible distance to each other.
in this case, the pair would be 12 and 12, so the greatest product is simply 144.
to verify this answer, you can try out different pairs.
for example, let's try 13 and 11.
13 * 11 = 143, which is less than 144. you can continue trying other pairs if you are still doubtful ;)
hope this helped! please let me know if you are confused about anything i did
