Frequently asked questions
What is rounding to the nearest thousand?
Snapping a number to the closest multiple of 1,000. The hundreds digit decides: 500 or more rounds up, so 15,500 becomes 16,000.
Why do salaries get quoted this way?
Round thousands are easier to remember and compare. Saying a budget is $16,000 communicates the scale instantly; the exact $15,512 can follow.
What happens exactly at 500?
It rounds up: 2,500 becomes 3,000. This half-up rule is the convention taught in schools and used in most everyday rounding.
Does it work for very large numbers?
Yes. Millions round the same way: 1,499,999 becomes 1,500,000, because only the last three digits decide the direction.
