## What is the value of 1 2 3 4 5+ 101?

Hence, the value of 1 – 2 + 3 – 4 + 5 – 6 + ….. + 101 is 51.

**What is the sum of the number 1 to 100?**

5050

The sum of all natural numbers from 1 to 100 is 5050.

### Whats 1 2 3 to a 100?

Gauss realized then that his final total would be 50(101) = 5050. The sequence of numbers (1, 2, 3, … , 100) is arithmetic and when we are looking for the sum of a sequence, we call it a series.

**What is the value of pi in mathematics?**

approximately 3.14

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.

## What is the value of (- 1 500?

The value of (-1)500 = -500…..

**What is the additive identity in whole numbers?**

zero

Additive Identity: It is the number which when added to another number gives you the number itself. Assume the whole numbers a, b. zero is the whole number which satisfies the condition mentioned in question. So, zero is the additive identity.

### Is 1/4 the same as 2/8?

In this case it is easy, because we know that 1/4 is the same as 2/8 : There are two popular methods to make the denominators the same: (They both work nicely, use the one you prefer.) Visit the Fractions Index to find out even more.

**What numbers did Gauss add together to get 101?**

Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101. 1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50 100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51 1 + 100 = 101 2 + 99 = 101 3 + 98 = 101 48 + 53 = 101 49 + 52 = 101 50 + 51 = 101

## What is the best way to show 1/2 as a fraction?

It is usually best to show an answer using the simplest fraction ( 1/2 in this case ). That is called Simplifying, or Reducing the Fraction We call the top number the Numerator, it is the number of parts we have. We call the bottom number the Denominator, it is the number of parts the whole is divided into. You just have to remember those names!
