+## \-\-- Day 2: I Was Told There Would Be No Math \-\--
+
+The elves are running low on wrapping paper, and so they need to submit
+an order for more. They have a list of the dimensions (length `l`, width
+`w`, and height `h`) of each present, and only want to order exactly as
+much as they need.
+
+Fortunately, every present is a box (a perfect [right rectangular
+prism](https://en.wikipedia.org/wiki/Cuboid#Rectangular_cuboid)), which
+makes calculating the required wrapping paper for each gift a little
+easier: find the surface area of the box, which is
+`2*l*w + 2*w*h + 2*h*l`. The elves also need a little extra paper for
+each present: the area of the smallest side.
+
+For example:
+
+-   A present with dimensions `2x3x4` requires `2*6 + 2*12 + 2*8 = 52`
+    square feet of wrapping paper plus `6` square feet of slack, for a
+    total of `58` square feet.
+-   A present with dimensions `1x1x10` requires `2*1 + 2*10 + 2*10 = 42`
+    square feet of wrapping paper plus `1` square foot of slack, for a
+    total of `43` square feet.
+
+All numbers in the elves\' list are in
+feet.
+How many total *square feet of wrapping paper* should they order?
+
+Your puzzle answer was `1588178`.
+
+## \-\-- Part Two \-\-- {#part2}
+
+The elves are also running low on ribbon. Ribbon is all the same width,
+so they only have to worry about the length they need to order, which
+they would again like to be exact.
+
+The ribbon required to wrap a present is the shortest distance around
+its sides, or the smallest perimeter of any one face. Each present also
+requires a bow made out of ribbon as well; the feet of ribbon required
+for the perfect bow is equal to the cubic feet of volume of the present.
+Don\'t ask how they tie the bow, though; they\'ll never tell.
+
+For example:
+
+-   A present with dimensions `2x3x4` requires `2+2+3+3 = 10` feet of
+    ribbon to wrap the present plus `2*3*4 = 24` feet of ribbon for the
+    bow, for a total of `34` feet.
+-   A present with dimensions `1x1x10` requires `1+1+1+1 = 4` feet of
+    ribbon to wrap the present plus `1*1*10 = 10` feet of ribbon for the
+    bow, for a total of `14` feet.
+
+How many total *feet of ribbon* should they order?
+
+Your puzzle answer was `3783758`.
+
+Both parts of this puzzle are complete! They provide two gold stars:
+\*\*
+
+At this point, you should [return to your Advent calendar](/2015) and
+try another puzzle.
+
+If you still want to see it, you can [get your puzzle
+input](2/input).

+## \-\-- Day 3: Perfectly Spherical Houses in a Vacuum \-\--
+
+Santa is delivering presents to an infinite two-dimensional grid of
+houses.
+
+He begins by delivering a present to the house at his starting location,
+and then an elf at the North Pole calls him via radio and tells him
+where to move next. Moves are always exactly one house to the north
+(`^`), south (`v`), east (`>`), or west (`<`). After each move, he
+delivers another present to the house at his new location.
+
+However, the elf back at the north pole has had a little too much
+eggnog, and so his directions are a little off, and Santa ends up
+visiting some houses more than once. How many houses receive *at least
+one present*?
+
+For example:
+
+-   `>` delivers presents to `2` houses: one at the starting location,
+    and one to the east.
+-   `^>v<` delivers presents to `4` houses in a square, including twice
+    to the house at his starting/ending location.
+-   `^v^v^v^v^v` delivers a bunch of presents to some very lucky
+    children at only `2` houses.
+
+Your puzzle answer was `2081`.
+
+## \-\-- Part Two \-\-- {#part2}
+
+The next year, to speed up the process, Santa creates a robot version of
+himself, *Robo-Santa*, to deliver presents with him.
+
+Santa and Robo-Santa start at the same location (delivering two presents
+to the same starting house), then take turns moving based on
+instructions from the elf, who is
+eggnoggedly
+reading from the same script as the previous year.
+
+This year, how many houses receive *at least one present*?
+
+For example:
+
+-   `^v` delivers presents to `3` houses, because Santa goes north, and
+    then Robo-Santa goes south.
+-   `^>v<` now delivers presents to `3` houses, and Santa and Robo-Santa
+    end up back where they started.
+-   `^v^v^v^v^v` now delivers presents to `11` houses, with Santa going
+    one direction and Robo-Santa going the other.
+
+Your puzzle answer was `2341`.
+
+Both parts of this puzzle are complete! They provide two gold stars:
+\*\*
+
+At this point, you should [return to your Advent calendar](/2015) and
+try another puzzle.
