What Is a Thousand in Math?

In math, “thousand” refers to the four-digit natural number 1000, often written as “1,000” in numerical notation. The comma in “1,000” signifies the division between place values of digits.

The term “thousand” is used to represent a quantity or a value equivalent to 1,000, a number consisting of four digits.

  • One thousand = 1,000
  • Two thousand = 2,000
  • Three thousand = 3,000

…and so on.

NOTE: Note that numbers with four or more digits, starting from 1,000, are written with a comma. This practice helps in understanding place values and periods, and thereby simplifying reading very large numbers. However, some American notations skip commas when writing four-digit numbers; they are typically used for numbers consisting of five digits or more. In some languages, the comma (,) is not used as a separator to prevent confusion with decimal placement.

Conclusion

In this article, we have learned about a thousand in math. The number 1,000 acts as a fundamental building block for comprehending our numerical system in the world of mathematics. Now, let’s solve some examples and practice problems to understand the concept better.

Solved Examples on Thousand

Example 1: Convert 3 km into meters.

Solution:

There are 1,000 meters in one kilometer.

To convert kilometers to meters, you can multiply the number of kilometers by 1,000.

3 kilometers = (3 × 1,000) meters = 3,000 meters

So, 3 kilometers is equivalent to 3,000 meters.

Example 2: Find the prime factorization of the number 1,000.

Solution:

To find the prime factorization of 1,000, we can start by dividing it by prime numbers.

1,000 = 2 × 2 × 250

1,000 = 2 × 2 × 2 × 125

1,000 = 2 × 2 × 2 × 5 × 25

1,000 = 2 × 2 × 2 × 5× 5 × 5

1,000 = 23 × 53

Example 3: Express the fraction $\frac{7}{1,000}$ as a decimal.

Solution:

To convert a fraction into a decimal, divide the numerator by the denominator.

7 ÷ 1,000 = 0.007
