Answer:

Neither is greater; they both have the same value: 5.

Explanation:

You want to know which is greater, |-5| or |5|.

Absolute value

The absolute value function removes the sign from any constant argument, so ...

|-5| = 5

|5| = 5

Both of these expressions have the same value, so neither is greater.

Additional comment

There's a little more to it. If the argument is negative, then the absolute value function returns the opposite. That is, |x| = -x when x < 0. Effectively, its definition is different for x<0 than for x≥0. This comes into play when you're solving equations and inequalities that involve the absolute value function.

In the above case, this means |-5| = -(-5) = 5.
