How to open Arithmancy doors

Arithmancy doors are essentially math problems in disguise. You're supposed to determine which animal around the frame corresponds to what number and then determine what numbers fit in the ? spots on the two triangles on the door's face. Even knowing all that, solving them isn't so simple. Here are the steps you need to take to solve any of them.

Step 1: Interact with the door to see the interior triangles.

Step 2: Add the two known numbers of each triangle together. If you see an animal and not a number, check this cipher to convert it into a number.

Step 3: Subtract the number inside the triangle from the sum you just got.

Step 4: Take those two new numbers and find which animal they correspond to.

Step 5: Locate the ? and ?? symbols on the walls nearby.

Step 6: Interact with each of them until they show the correct animal.

Step 7: Once both have the correct animal showing, the door will open and you can claim the loot inside.

How to get Structural Materials in Starfield
Starfield planet.

Starfield has a massive expanded the amount of things you can build and craft. From entire Outposts to weapon mods and research projects, everything you want to craft will require specific materials to create. These materials will be found all over the various planets, either as lootable objects, ores you need to mine, or even as items you can purchase from various vendors, but some will always be harder to find than others. Structural Materials, while not the rarest resource, are used in nearly every aspect of Outpost building and upgrades. If you're running low on this crucial building block, here's how to get more Structural Materials in Starfield.
Ways to get Structural Materials

Like any resource in Starfield, there's more than one way to get your hands on Structural Materials. The easiest, but most expensive, will be to simply buy them from one of the many shops around the galaxy. Vendors' stock is slightly variable from day to day, but you can typically rely on any of your more "general" stores to carry this common material, such as the Jemison Mercantile in New Atlantis or Shepard's General Store on Akila. Each vendor will only hold a specific amount, so if you need a lot, you will need to do a little legwork. After buying out everything a vendor has, if you wait for 24 hours at a chair or bed, you can go back and their stock will be replenished.

For the most part, the main questline in Starfield won't challenge you too much in terms of puzzle-solving. Missions tend to boil down to getting an objective, fast traveling to a location, and following your marker until you collect an Artifact. Since you can only unlock all the powers by going through the main quests, you will at least want to complete most of them before going off and doing all the faction missions, outpost building, or general space exploration. There's one mission, though, that can be a roadblock if you're not extra observant and invested in reading all the lore. If you don't know the answers to opening the Pilgrim's Computer in Starfield, here is all the information you need.
Pilgrim Computer's answers

After you arrive at Pilgrim's Rest and explore, you will be led to the small base that's full of notes, among dozens of other items.

Here are all the questions you will be asked, and the correct responses:
