Question

Which three numbers (0 through 9) do you need to replace the question marks with to have the answer be the largest number possible? (No repeat numbers.)

Answer 1

Answer:

9,9,0

Step-by-step explanation:

The first two are being added, so we want them to be the highest possible, to get the highest, or greatest, number. We then are subtracting, so we want the smallest number, as we’ll get the highest if we’re taking away the least. Henceforth, we substitute a 0 in the place of the ? in 384?9. It gets us 38419, the highest number I was able to find.
