Doing math in a natural language is sometimes difficult. Luckily, we can get rid of ambiguities by trying to formalize statements.I hope we can agree on the following:<blockquote>If x<sub>0</sub>.x<sub>1</sub>x<sub>2</sub>x<sub>3</sub>x<sub>4</sub>x<sub>5</sub>...... is the digital expansion of π, then a "infinite and unbroken sequence of digits in the representation of π (not starting with the first significant digit) equal to π" is given by x<sub>n</sub>x<sub>n+1</sub>x<sub>n+2</sub>x<sub>n+3</sub>x<sub>n+4</sub>x<sub>n+5</sub>......, with x<sub>n</sub>=3, x<sub>n+1</sub>=1, x<sub>n+2</sub>= 4, x<sub>n+3</sub>=1, and so on and <i>n</i> being a natural number</blockquote> | Doing math in a natural language is sometimes difficult.
