The number of ways to arrange ten people in different positions is given by the factorial of 10, denoted as 10!. 
The factorial of a number is the product of all positive integers up to that number.

$10!=10\times 9\times 8\times 7\times 6\times 5\times 4\times 3\times 2\times 1$

Calculating this, we get:

$10!=3,628,800$
