30 x 1000 = 30000
30 times 1000 is 30000. The three zeros from the 1000 move straight onto the 30. Below are the working, two ways to check it in your head, and a calculator you can reuse.
30 × 1,000 = 30,000
Adding 30 to itself 1,000 times gives the same answer.
30 x 1000 = 30000
The three zeros in 1000 attach to the 30, giving 30,000 – thirty thousand.
Two ways to see it
- Strip the zero off 30 first: 3 x 1000 = 3000, then put the zero back to reach 30000.
- Or read the pair as 3 x 10000. Either route ends with a 3 followed by four zeros.
That second form is also how 30000 is written in scientific notation: 3 x 10 to the fourth power.
What 30000 is
- 30000 seconds is exactly 8 hours and 20 minutes.
- It is double 15 x 1000 = 15000 and ten times 30 x 100 = 3000.
- Fully factored it is 2 x 2 x 2 x 2 x 3 x 5 x 5 x 5 x 5. The only odd factors are 3 and 5, so 30000 divides evenly by 3, by 15 and by every power of 5 up to 625.
Not the same as
- 30% of 1000 is 300. Percent means per hundred, and that costs you two zeros.
- 100 x 300 reaches the same 30000 from a different pair.
