Final answer:
The absolute value of 10 is 10 because absolute value indicates the magnitude of a number without sign, and 10 is already positive.
Step-by-step explanation:
To solve the equation |10| = _, we need to understand that the absolute value symbol (| |) represents the magnitude of a number without regard to its sign. It is always positive or zero. Since 10 is a positive number, the absolute value of 10 is simply 10. To find the absolute value of a number, we use the notation |x|, where x is the number. Therefore, the solution to |10| is 10.
