b. \( |170|-|-4| \)

First, let's break it down with some simple math. The absolute value of 170 is 170, and the absolute value of -4 is 4. Now, plugging those values back into the expression gives us \( 170 - 4 \), which equals 166! It's like peeling away the layers of an onion—what's left is the good stuff. Now, if you're ever in the kitchen and need to measure out ingredients, remember that using absolute values can save you from adding or taking away wrong amounts! It’s all about keeping things positive and measuring accurately—whether in math or in cooking!
