No, math is not cryptic.

## A more thorough response to your inquiry

Mathematics is not cryptic but it may seem that way to those who haven’t had the opportunity to learn and experience its beauty and practicality. The subject has been studied for centuries and is an essential tool in many areas of science, engineering, and business. According to John von Neumann, “In mathematics, you don’t understand things, you just get used to them.”

Here are some interesting facts that demonstrate the everyday usefulness and fascinating nature of math:

- Cryptography, which involves coding and decoding information, relies heavily on mathematics.
- The Fibonacci sequence, which is a series of numbers in which each number is the sum of the two preceding numbers, is found in a variety of natural patterns such as the arrangement of leaves on a stem and the spirals of shells.
- The ancient Greeks were enthusiastic about mathematics and made many important contributions to the subject, including geometry, logic, and number theory.
- The concept of zero, which is crucial to modern mathematics, was developed independently in both India and Central America around the same time.
- NASA uses mathematics to navigate its spacecraft and predict the paths of asteroids and comets.
- Cryptic crosswords involve solving clues that require knowledge of mathematical concepts such as geometry and probability.

In conclusion, math is a powerful tool that can be applied to many areas of life and is far from being cryptic. As Galileo Galilei once said, “Mathematics is the language in which God has written the universe.”

Here is a table demonstrating how math is used in various fields:

Field | Use of Math |
---|---|

Engineering | Designing structures and machines, calculating forces and loads |

Economics | Analyzing trends and predicting future outcomes, optimizing financial decisions |

Medicine | Creating models of biological systems, analyzing medical data |

Computer Science | Programming algorithms and data structures, analyzing and processing data |

Physics | Describing the behavior of the natural world, predicting the outcomes of experiments |

## See a video about the subject.

The video presents a math quiz consisting of a Sudoku using numbers one through nine and additional equations on the right side. The goal is to make the equations work while following normal Sudoku rules. The presenter uses logical reasoning and Sudoku rules to solve the puzzle, starting by deducing that the tens digit of a two-digit number must be one and ruling out other possible numbers based on the Sudoku rules. The presenter struggles at times but ultimately solves the puzzle using similar methods, also remarking on the delightful interaction between the arithmetic quiz and Sudoku.

## Check out the other answers I found

By the time I posted this (in an incomplete state, though it’s done now) others had also solved the first 5 clues. I shan’t reproduce those solutions here. Here are the last three.

Arctan maps every other arccot into an embankment, too (8)

ABUNDANT. (Take the word ARCTAN. Replace RCT, found as alternate letters of ARCCOT, with BUND, a type of embankment. Then add T, which I guess comes from “too” in the clue though I don’t quite understand how.)

Heated rant with part of Ulam spiral (7)

NATURAL. (Anagram of RANT ULA).

Curse without Germain’s initial initial (4)

PELL. (SPELL without the initial letter Sophie Germain’s first, i.e., initial, name.)

So, what’s next? Well,

all the answers are names of particular sets/sequences of integers, and the question directs us to OEIS. And of course we have those italicized words. I confess that before doing what I’m about to describe I tried a couple of other things that incorporated most of the right ideas “but not necessarily in the right o…

*zero-knowledge proof*, and it has many applications in digital cryptography. Let me briefly explain.

*underground chamber*," is one. The element krypton would be another correct guess, and so would apocrypha, which can mean "writings of dubious authenticity."

*digits are used to represent other digits*. A long division in which most or all of the digits are replaced by symbols (usually asterisks) to form a cryptarithm. A rare variation where a formula is written, and the solution is the corresponding cryptarithm whose solution is the formula given.

*abrupt; terse; short*: a cryptic note. secret; occult: a cryptic writing. Zoology. fitted for concealing; serving to camouflage. a cryptogram, especially one designed as a puzzle. 1 enigmatic, perplexing.
