I need an explanation on question #2 from the 4th grade Arithmetic Operations chapter test.
The given digits are 2, 0, 3, 5 and 6.
The smallest and largest six digit number such that digit 2 is repeated twice are
Largest six digit number = 653220
Smallest six digit number = 202356
Thus required difference = 653220 – 202356
Hence the required difference is 450864.
