0 through 9 is 10 digits.
For the first number you have 10 choices, same for the second and third and forth, so your total amount of possible combinations (assuming you can repeat) is:
10 * 10 * 10 * 10 = 104 = 10,000 (ten thousand)
If repetition is not allowed, then for the first you have 10 choices, second you have 9 (every digit except the one you used for the first), third you have 8 and forth you have 7, giving you:
10 * 9 * 8 * 7 = 5040
To total numbers from 1 through 100 using a FOR-NEXT loop, you would initialize a variable to store the sum and then iterate through each number from 1 to 100. In each iteration, you would add the current number to the sum variable. Here's a simple pseudocode example: sum = 0 FOR i = 1 TO 100 sum = sum + i NEXT i After the loop, the variable sum will contain the total of numbers from 1 to 100.
place the digits 1 through 9 into three 3-digit numbers of an addition problem only using 1 through 9 once each
In QBasic, you can print even numbers using a simple loop. For example, you can use a FOR loop to iterate through a range of numbers and then check if each number is even by using the modulus operator (MOD). Here's a sample code snippet: FOR i = 1 TO 20 IF i MOD 2 = 0 THEN PRINT i NEXT i This code will print all even numbers from 1 to 20.
To print even numbers in a loop in QBasic, you can use a FOR loop to iterate through a range of numbers and check if each number is even. An even number can be identified using the modulus operator (MOD). Here's a simple example: FOR i = 1 TO 20 IF i MOD 2 = 0 THEN PRINT i END IF NEXT i This code will print all even numbers from 1 to 20.
You can make 27 unique three-digit numbers using the three digits 0, 1, and 2.i.e. for each of the three digits abc, there are 9 possible orders of those, from aaa to ccc.The 9 starting with 0:000001002010011012020021022* the combinations are the same as the numbers 0 to 26 expressed in base 3 (000 to 222)26 base 3 = 222 = 18 + 6 + 2 = 26
1000
There is only one combination. In a combination the order of the numbers does not matter so the only combination is 0123456789. This is the same as 1326458097
Each digit can appear in each of the 4 positions. There are 9 digits, therefore there are 9⁴ = 6561 such combinations.
It depends. If you can only use each number once, there are 720 combinations. If you can use numbers multiple times, then there are 1000 combinations, by using all numbers from 000 to 999.

To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, 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). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.
10!/3! = 604800 different combinations.
To calculate the number of license plate combinations using three letters and four numbers, we consider the possibilities for each part separately. There are 26 letters in the English alphabet, so for three letters, there are (26^3) combinations. For the four numbers, using digits 0-9, there are (10^4) combinations. Therefore, the total number of combinations is (26^3 \times 10^4), which equals 17,576,000 combinations.
To find the total number of combinations using three series of numbers, each ranging from 1 to 13, you multiply the number of choices for each series. Since each series has 13 options, the total combinations are (13 \times 13 \times 13), which equals (13^3 = 2,197). Therefore, there are 2,197 possible combinations.
In other words, how many 4 digit combination locks are there using the digits 0-9 on each wheel. There are 10×10×10×10 = 10⁴ = 10,000 such combinations.
There are ten combinations: one each where one of the ten digits, 0-9, is excluded.
