How Can You Solve the Classic 10 Digit Number Puzzle? Solution
This number puzzle is quite tricky, and we'd like to invite you to give it a go and see if you can find the answer.
The task is to find a special 10-digit number. It needs to follow two rules: First, it must be a "polydivisible" number, which means the first part of the number must be divisible by the number of digits it has. Second, it must use all the digits from 0 to 9, making it "pandigital."
To solve this, we start by making sure the last digit is 0 because it must be divisible by 10, and the fifth digit has to be 5 to be divisible by 5. This reduces the possibilities to about 40,000. Then, we arrange the even digits in even spots and odd digits in odd spots. The fourth digit can be 2 or 6 to be divisible by 4. The fourth, fifth, and sixth digits are 2, 5, and 8 in some order.
Next, we work on making the first eight digits divisible by 8, narrowing it down to eight potential numbers. The last even digit goes in the tenth spot, leaving three odd digits to complete the number. By checking their sums, we get 10 possible numbers.
Finally, we check which of these 10 numbers can be divided by 7, and the answer is 3,816,547,290, the only number that meets all the rules.
Calculate the Outcome of 144 ÷ 12 + 6 x 3 - 9 ÷ 3=?
To find the solution, follow the order of operations. Begin with the divisions and multiplications from left to right: 144 ÷ 12 equals 12, and 9 ÷ 3 equals 3. Now the equation becomes 12 + 6 x 3 - 3. Next, perform the multiplications and additions/subtractions from left to right: 6 x 3 equals 18, and 12 + 18 equals 30. Thus, the solution is 30.
Determine the Value of 168 ÷ 7 + 8 x 2 - 14 ÷ 2?
Stick to the order of operations as usual. Start with the divisions and multiplications from left to right: 168 ÷ 7 equals 24, and 14 ÷ 2 equals 7. Now the equation becomes 24 + 8 x 2 - 7. Next, perform the multiplications and additions/subtractions from left to right: 8 x 2 equals 16, and 24 + 16 equals 40. Therefore, the solution is 40.
