Question

Write all possible 4 digit numbers using 6,1,0,8

Answer 1

Answer:

1068, 1086, 1680, 1608, 1806, 1860, 6081, 6018, 6108, 6180, 6801, 6810, 8016, 8061, 8610, 8601, 8106, 8160

Step-by-step explanation:

We cannot make any numbers with 0 in the thousands place because if zero is written to the left of any number, it is not considered. Thus, if we make any number starting with 0, it will actually be a digit in the hundreds place. e.g. - 0168 = 168 which is not a 4 digit number
