## What positive number doubles when last digit becomes first?

The new number has 2(2) = 4 as its last digit. The last digit of the new number is also the tens digit of the original number, as the new number is formed by shifting the digit a to the front. Therefore, the tens digit of the original number is 4….Proof of minimality.

**What number is the last number?**

A googol is the large number 10100. In decimal notation, it is written as the digit 1 followed by one hundred zeroes: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.

### How do you add the first and last digit of a number?

Algorithm to find the sum of first and last digit using the loop:

- int n = 1234;
- lastDigit = num \% 10.
- sum = firstDigit + lastDigit;

**What does based on your last like mean?**

NFL Polls Now on Instagram: “The last digit of your like (or comment if you can’t see likes) is the team that you have to be a fan of! Which team do you have to be a…” nflpollsnow. 10,641 likes. nflpollsnow The last digit of your like (or comment if you can’t see likes) is the team that you have to be a fan of!

#### What is the last digit of 17 17?

Hence 17^17=17^(4.4+1), so the unit place will repeat after 4 circles. hence 17^1 and 17^17 will have same digit in the unit’s place. So the answer is 7.

**How do I get the last digit of a number in CPP?**

To find last digit of a number, we use modulo operator \%. When modulo divided by 10 returns its last digit.

## What is the last countable number?

There is no biggest, last number … except infinity. Except infinity isn’t a number. But some infinities are literally bigger than others.

**Where do the numbers end?**

The sequence of natural numbers never ends, and is infinite. OK, 1/3 is a finite number (it is not infinite). There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.

### How do you find the second last digit of a number?

Steps

- Let N be the input number.
- If N is a one-digit number, return -1.
- Set N = N / 10. This step removes the last digit of N.
- N \% 10 gives us the last digit of N. Since we have already removed the last digit of N in the previous step, N \% 10 is equal to the second last digit of the input number.
- Return N \% 10.

**How do I get the last digit of a number in C ++?**

C Program to find first and last digit of a given number using loop:

- #include
- int main()
- {
- int n, sum=0, firstDigit, lastDigit;
- printf(“Enter number = “);
- scanf(“\%d”, &n);
- // Find last digit of a number.
- lastDigit = n \% 10;

#### How do you find the last digit of a number?

To find last digit of a number, we use modulo operator \%. When modulo divided by 10 returns its last digit. Suppose if n = 1234. then last Digit = n \% 10 => 4. To finding first digit of a number is little expensive than last digit.

**How to find last digit of a number using modulo?**

To find last digit of a number, we use modulo operator \%. When modulo divided by 10 returns its last digit. Suppose if n = 1234 then last Digit = n \% 10 => 4

## Is My Number the smallest positive number?

If the last digit of this positive number becomes the first digit, the resulting number is exactly twice as large. My number is the smallest positive number with this property. What is my number?

**What is the tens digit of the original number?**

The last digit of the new number is also the tens digit of the original number, as the new number is formed by shifting the digit a to the front. Therefore, the tens digit of the original number is 4. We can use this information and then continue the multiplication to find the next digit.
