To calculate the total number of combinations of a 4-digit number using the numbers 1-9 and 0, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). So, the total number of combinations is 10^4 = 10,000. Each combination will be unique, as the order of the digits matters in a 4-digit number.
