2dtx.com is a website that is about mathematics, the website was founded in 2011.

Why it Failed Its Math Test[edit | edit source]

  1. Their prime factorization calculator is incorrect most of the time.
    • If you type a number that's 44 digits or more, it incorrectly states it as a prime number. [1]
    • If you type a number only factorized by prime numbers 37 or above, it also states it as a prime. [2] [3]
    • Sometimes it incorrectly states the factors of some numbers.
  2. The admins on the website have been inactive since 2015, this makes the website very outdated, that's 8 years of no activity, despite a minor update to the website's style and layout in 2021-2022.
  3. There is only 7 pages on the website, that's just plain lazy, and boring.
  4. If you click on the Arabic section of the website, it has nothing to do with Arabic. it just redirects to a calculator of Roman Numerals. [4]

Redeeming Qualities[edit | edit source]

  1. The factorization calculator is correct.
  2. The prime factorization calculator used to state that numbers only factorized from prime numbers 11-31 and above was thankfully fixed in 2015. Unfortunately, it wasn't fixed in prime numbers only factorized by prime numbers 37 and above.

Trivia[edit | edit source]

  1. The same owners of the website also own Coolmathgames9.com, which is still bad enough.
