Quick-Start Guide. When you enter an equation into the calculator, the calculator will begin by expanding (simplifying) the problem. Next, it will attempt to solve the equation by using one or more of the following: addition, subtraction, division, factoring, and completing the square.uick-Start Guide.

Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element's symbol.
In chemistry, we often use symbols to identify elements and molecules. Molecular formula and empirical formula are two such symbolical methods we use to represent molecules and compounds in an easy way. Molecular formula is the formula showing the type of atoms and number of each atom connected in the molecule. Therefore, it gives the correct stoichiometry of each atom. The atoms are depicted by their symbols, which are shown in the periodic table. And the numbers of atoms are written as subscripts.
