The NumWorks calculator is conducting the same survey to implement the multiplication symbol, according to the results of the same

The formal mathematical language, the symbol of multiplication is an intermediate point (·) or the symbol (+) rotated 45 ° (× ASCII # 215), both (·) and (×) it is only written to give clarity in a definition, but not in everyday use. Although the symbol (×) should be better used best for the Cartesian product or cross product
To give taste to several input styles, calculators and mathematical packages have to allow the interpretation of asterism (*), as well as the intermediate point (·) as multiplication symbols

84/6·x + 84/12·x + 84/7·x + 5·84 + 84/2·x + 4·84 = 84·x
84/6*x + 84/12*x + 84/7*x + 5*84 + 84/2*x + 4*84 = 84*x
84/6×x + 84/12×x + 84/7×x + 5×84 + 84/2×x + 4×84 = 84×x

But they have to show by default only the intermediate point in the output (·), since it occupies less horizontal space and the mathematical expression is more readable
The survey should also ask about the use of the standard symbol ÷ as a division operator as linear input (Algebraic mode)

84÷6·x + 84÷12·x + 84÷7·x + 5·84 + 84÷2·x + 4·84 = 84·x

LO SUFICIENTEMENTE BUENO ES ENEMIGO DE LA EXCELENCIA.
