Photomath and Slide Rule Competition Oct 2023

Performing complex calculations

Recall the app called Photomath, available on Android and iPhone. I’m using an iPhone.

Also recall the Texas UIL Slide Rule contests from way back.

Let’s try one of the old test questions, say Question 74.

  • According to the test PDF, the answer is 1.68 (1.66 to 1.70)
  • According to PhotoMath, the answer is 1.68735
  • According to Python, the answer is 1.68735322

PhotoMath scans and parses the problem from my paper copy of the test. No typing required — not a single character.

PhotoMath simplifies the expression and determines the result.
