To find the product of a 2-digit number and a 4-digit number that is approximately 500,000, we need to consider the magnitude of the numbers involved. Since a 2-digit number ranges from 10 to 99 and a 4-digit number ranges from 1000 to 9999, their product will be in the range of 10,000 to 99,000,000. To get a product around 500,000, we can estimate that the 2-digit number is around 50 and the 4-digit number is around 10,000. Therefore, the product of a 50 and 10,000 is 500,000.
Yes, unless the 3 digit number is negative, or a decimal.
The largest 10-digit number with no digit repeated is 9876543210 !
To write pseudocode for reversing a given number, first initialize a variable to store the reversed number and set it to zero. Then, use a loop to extract the last digit of the number (using modulo operation), append it to the reversed number, and update the original number (by dividing it by 10). Continue this process until the original number becomes zero. Finally, output the reversed number. Here’s a simple pseudocode example: function reverseNumber(number): reversed = 0 while number > 0: digit = number % 10 reversed = reversed * 10 + digit number = number // 10 return reversed

Find a four digit number whose digits will be reversed when multiplied by nine?
90

2178. 2178 x 4 = 8712
The four-digit number that gets reversed when multiplied by 9 is 1089. When you multiply 1089 by 9, you get 9801, which is 1089 reversed. This property makes 1089 a unique and interesting number in this context.

47 Impossible problem!
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
