@pwharris 15k and 9 k is 24k, or 24,000. Set it aside for later. Now let's worry about 938 and 491... If I take 9 from 938 and put it on 491 I get 929 and 500, which is 500 and 429 and 500, which is 1000 and 429. So, 24,000 + 1000 + 429 is equal to 25,429 #mathstratchat

15,938+9,491 (rearrange digits to get largest 1st part) =19,991+5,438 (readjust to make multiple of 10,000 by +9,-9 20,000+5,429=25,429 Messy and needed jottings #mathstratchat
