Mixed fractions
From Why start at x, y, z
Adjacency means different things depending on the context:
- \( 2x \) means \( 2 \times x\).
- \( 2 \frac{2}{3} \) means \( 2 + \frac{2}{3}\).
This results in the coincidence \( \sqrt{2 \frac{2}{3}} = 2 \sqrt{\frac{2}{3}} \).
Adam Atkinson says that mixed fractions aren't understood everywhere, which prompted Christian Lawson-Perfect to run a survey on whether they exist[1].
