For example, 3*/4+(4/0)-/7.59 is a nonsense collection of symbols and numbers.
Latin was the language spoken by the Romans so the obvious Latin mathematical symbols would be the Roman numeral system. Many of our mathematical words such as addition, subtraction, division, multiplication, fraction, decimal, percentage, calculate ........ etc. come directly from the Latin language.
