Here comes the pitch.....and, oh! Falling just short. So, here's how you would solve this problem: You have a single piece of rope, measuring 84 inches. Let's call that the total length. You need 6 pieces each measuring 8 inches. We'll call the sum of that the cut length. What you need to do to find out the amount you have left over is to subtract the cut length from the total length. How do you find the cut length? You can multiply, like this, since you know you need six pieces, of eight inches length each. \[l _{total} = 84 i n .\]\[l _{cut} = 6 * 8 i n. = 48 i n.\]\[l _{remain} = 84 - 48 = 32 i n.\] Does this make sense?
