Why do these two multiplications behave this way?
\(431 * 52\) is \(99\) more than \(421*53\)
\( 531*42 \) is \(110\) less than \(431 *52\)
WHY?
Is \(431*52\) the largest product using digits 1, 2, 3, 4, 5?
(1) 431x52 is 99 more than 421x53 (2) 531x42 is 110 less than 431x52 WHY? Is 431x52 the largest product using digits 1,2,3,4,5?
