What is the smallest number you can add to 456 to get a sum that uses the digits 4?

Let's go through the process: Add 1 to 456: 456 1 = 457 456+1=457 (does not contain the digit 4) Add 2 to 456: 456 2 = 458 456+2=458 (does not contain the digit 4) Add 3 to 456: 456 3 = 459 456+3=459 (does not contain the digit 4) Add 4 to 456: 456 4 = 460 456+4=460 (contains the digit 4) Here, adding 4 gives us 460, which includes the digit 4. Therefore, the smallest number you can add to 456 to get a sum that uses the digit 4 is 4 4 Read More...tinyurl .com/sx3dkfpw
