I would argue that there is no answer because it is not written in any standardized form of mathematics. There is a reason why no math teacher on earth would accept this as an equation, it is ambiguous. Unlike languages that can over time due to the common use of a term or word by common people, see the Oxford dictionary's inclusion of slang like ain't, mathematical notation can only change by the agreement of scholars. Those that shout PEMAS as the answer need to learn math beyond the 4th grade. When math is used for a purpose, such as engineering, it needs to be clear and unambiguous. Proper notation allows for the identification of units of measure. We don't use "slang" math notation for a reason if it isn't agreed upon than it can become useless.
