What can be the maximum sum of digits for a 4 digit number?

R D Sharma – Mathematics 9 The largest four digit number is 9999, and thus, a maximum value can be obtained by adding 9999 and 9999, and the resultant number will be having the maximum number of digits. Therefore, the maximum number of digits of the resultant number, when two four-digit numbers are added is 5.

When you multiply a 4 digit number by a 2 digit number?

Specifically, we learned that when multiplying a four-digit number by a two-digit number, each of the digits in the two-digit number, starting with the digit in the ones place, will get their turn to multiply. You then add the two answers together to get your final answer.

What is the product of largest 4 digit number and smallest 2 digit number?

hey mate !!! product of these = 9999×10 = 99990.

How do you find the maximum number of digits?

So for maximum number of digits we have to add two greatest 6 digit numbers and for minimum number of digits we have to add two smallest 6 digit numbers. So the addition of two greatest 6 digit numbers is = 999999 + 999999 = 1999998.

What can be the minimum sum of digits for a 4 digit number?

Hope this helps. The minimum number of digits in a sum of any two four digit numbers are 4 and the minimum number of digits in a sum of any two four digit numbers are 5.

How many numbers can you make with 3 digits?

There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times.

How to find the product of the digits of a number?

Given a number, the task is to find the product of the digits of a number. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Get the rightmost digit of the number with help of remainder ‘\%’ operator by dividing it with 10 and multiply it with product.

What are the properties of 4 digit multiplication?

When a certain four-digit number is multiplied by 4 its digits appear in reverse order. It also has the following properties. It’s first digit is a quarter of the last one. And its second digit is one less than the first.

What is a 4 digit number less than 2500?

Since it’s 4 Digit Number and since after multiplication also it has to be a 4 Digit Number, it’s easy to see that the Number has to be less than 2500 since 2500 * 4 = 10000. The Number also can’t be starting with 1, as any Number when multiplied by 4, can’t result into an odd number.

How to increase the sum of the digits of a number?

When the number of digits of a number exceeds , we can’t take that number as an integer since the range of long long int doesn’t satisfy the given number. So take input as a string, run a loop from start to the length of the string and increase the sum with that character (in this case it is numeric) Below is the implementation:
