Can you read garbled arithmetic?

We randomly scramble the spelling of arithmetic questions and ask both AI models and humans to answer them. This experiment measures how accuracy degrades as corruption increases.

You'll see 19 questions, each with a different level of character noise. Answer as best you can — no calculators needed, these are simple arithmetic problems.

Some examples of what you might see:

• two plus threeε = 0.00
• twq pluz thrdeε = 0.10
• xwb pquz thrneε = 0.25
• xkg rqbz nvmoeε = 0.45
