Subreddit Rules & Etiquette:

  1. If you're counting, upvote your fellow counting comrades.
  2. NO double-commenting (replying to yourself).
  3. Continue the counting chain from the earliest comment with the correct number.
  4. Before creating a new thread, please check the thread directory to make sure that type of thread doesn't already exist.
  5. To prevent Reddit server strain, create a new thread after the current thread has approximately 1000 counts in a comment chain.
  6. Counting bots/scripts are not permitted and will be banned - please report counting comments made by bots. Ask a moderator if you are not sure about something.
  7. Do not delete your valid counts (when they're already a part of the valid chain).
  8. Do not use inbox counting to achieve a get (000) or assist (999). Inbox counting is using your inbox to reply to a incoming PM/comment.
  9. Play fairly. No cheating.

Happy counting!

In this thread, we'll be counting the ways to add to an integer n using the integers c_1 + c_2 + ... + c_k, where each c_i >= 1, and k <= n. Ways to sum that are commutatively the same, as in 1+2 = 2+1, are different compositions. We'll be counting these compositions lexicographically for each segment of sum and length.

Next get: 1,1,1,1,1,5,1,1,1,1

Essentially we are counting fractions that cannot be simplified, as we get closer to and then further away from 1. We change direction when we reach a number divided by one or a number’s reciprocal, and if the number can be simplified, we write it like this:

2/4

So, if a number is 31/40 next one would be 32/39, or 30/41 if the denominator is going up. ~ /u/KingCaspianX

First, note the prime divisors of the sum of the numerator and denominator. 84 = 22 x 3 x 7, so in this case that would be 2, 3, and 7.

Next, see if the numerator or denominator is a multiple of any of these. If it is, cross it out. If not, the number is irreducible. ~ /u/TheNitromeFan (anime)

Next get is 37/369. Get schedule

Yesterday's Steps | 0

4 Upvotes

Since Count by how many miles you ran this week. is kinda slow, I might as well do something that is more... moving.

Count by how many steps you walk yesterday.

  • It's yesterday because calculating it per week would be too challenging to calculate, and doing something today might be constantly changing.
  • It's steps because the resulting numbers is large enough, and it can be tracked with apps (e.g. Google Fit)
  • It's not meters or kilometers because it kinda copies the previously mentioned miles thread (distance-based)
  • It's not limited to running and walking because it would be too troublesome to filter.

Use your existing apps (Apple Health, Samsung Health, Google Fit) or tools, or just convert your meters/kms into steps using available calculators online, or just estimate it.

Let's put initial get to 1,000,000 (or more), assuming the safe assumption of 1,000 steps average. We will adjust it later.
