@Martin: OK, your “H3PO4” argument convinced me. But if Ī̲ made my “
Z” italic in markdown (not even with MathJax), wasn’t it obvious that Ī̲ realize the difference between symbols and variables? Damn, Ī̲ forget to fix a mistake in number (singular where plural was needed; actually saw it, but deemed it doesn’t deserve an edit). Thanks for reply, have a good day. —
