I have been advised by my expert pal...
No. You continue to ignore the evidence that you are not consulting with an expert. You continue to substitute the non-credible statements of this purported expert in lieu of the evidence that would prove your claim. No one is obliged to entertain your anonymous and clearly bogus hearsay.
...that one can use Microsoft Equation Editor to format maths symbols.
That is a true statement, but it does nothing to address my rebuttals or to advance your argument.
He's not going to do it in a WhatsApp message.
Asked and answered. When using methods that do not allow or easily facilitate the proper symbols, there is an accepted system of substitutions using plain IEC 8859-1 characters. We all know them. We all use them. We have done so the same way for decades. When approximating multiple primes, we do not combine single- and double-quotes in any form. We use exclusively single quotes.
When using smart input devices that rewrite characters, we do not allow them to rewrite notation to be wrong. We are sometimes forgiving if the glyph is close enough, but if the glyph is rewritten to resemble a wrong symbol, that is not allowed. Again, correcting this has been second nature for a decade. This is especially important when the purpose of the message is to instruct the receiver in what the proper notation looks like, not to communicate a separate idea using the notation.
Your purported expert did use WhatsApp, and committed two beginner's mistakes while using it to write mathematical notation. These are long-solved problems, and long-established conventions. It's not as if mathematicians, physicists, scientists, and engineers don't use WhatsApp and other messaging systems to communicate mathematically-notated things. We've always used every medium that is available, and we've always followed the conventions that we've evolved to cope with the limitations and frustrations of those media. You're posturing your advisor as someone who necessarily would have been part of that community, and therefore learned and practiced these conventions.
There is no expert who confirmed your ″-for-minutes usage. Give it up.
