When Matthew eats at a buffet, he has one serving of each dish, but never goes back for seconds.

When asked the name of his favorite animal, Matthew lists 26, each starting with a different letter.

What changes can be made to the letters and/or numbers below to make Matthew happy?

      4 x 
    7 x x
x x x x x

Matthew does not like repetition. He prefers one of each. Since there are 10 spaces, he would like to use 0-9 once each.

Keep the 4 and the 7 and replace all the x's

46 multiplied by 715 = 32890
