What is the absolute value of -7?

The absolute value of a number is defined as its distance from zero on the number line, regardless of direction. This means that the absolute value is always non-negative.

For the number -7, its absolute value is determined by removing the negative sign, which gives us 7. Therefore, the absolute value of -7 is 7. This is why the correct answer is 7.

The concept of absolute value can be particularly useful in various mathematical contexts, such as solving equations and understanding distances. It helps to express quantities in a standard format without considering their sign, ensuring that distance and magnitude are represented accurately.
