That’s a problem with grammar and language; not math.
The agenda behind the pamphlet is obvious. I liked this gem from the page at issue:
>Schooling as we know it began during the industrial revolution, when precision and accuracy were highly valued. What are the myriad ways we can conceptualize mathematics in today’s world and beyond?
These thing WERE highly valued? They are no longer? And weren’t they valued BEFORE the industrial revolution? Indeed, was not the Industrial Revolution possible in the first place due to the high value put on precision and accuracy?
