So in the case of origami, you need to see 'Does this actually look like a crane? You have a square plot of land that is surrounded by a fence on all sides. The fact that it's square is important, or at least it seems like it might be important. One of the keys there is 'all sides.' Another is 'your next-door neighbor' - so we are going to underline 'next-door neighbor' because that means he's right next to you.
' In the case of a math problem, you need to look at all of the little details and make sure that your solution fits all of those from the original problem. One of your next-door neighbors has a rectangular plot that is the exact same size and same dimensions as yours. What percentage of his fence have you already completed for him? He's not across the street, there's not a lot of land between you guys, he's right next door.
What is the equation of the line in slope-intercept form?

If you don't know what you're solving, you can't solve it.
So I'm going to highlight 'what percentage of his fence have you completed for him already.' The second big key is to draw it out. I'm going to draw out a square plot of land and call it mine.
I've completed one side, and he needs four sides total. Then I'm going to fold up each side to make an open box. This sounds a little bit more complex, but let's remember our keys. That sounds about right, and there, the corners are gone. If I just cut 1 centimeter off each of the corners, then I know that the whole width is still going to be 8 centimeters, but the width at the edge here is going to be 6 centimeters.
So 1 divided by 4; I've completed 25% of his fence for him. If I look at my drawing, with my 25% that I've completed for him, I see that here is my plot of land and here is his plot of land. (Check.) A next-door neighbor (check) has a rectangular plot (okay, a square is a rectangle, check), and it's the same size and dimensions as mine. My diagram fulfills all of the requirements from here. First, I'm going to pull out important information. I don't know if I'm going to need this 40 centimeters squared, so I'm not exactly going to include that, but I'm going to keep in my head that I know that. It's got a width of 8 centimeters and a height of 5 centimeters, and I'm going to cut 1-centimeter squares from each of the corners. Similarly, I know that the whole height is going to be 5 centimeters, but I've cut 1 centimeter from each side, and so the height right here is going to be 3 centimeters. That rectangle, at least in our diagram, had an area of 40 centimeters squared.
