Basics of Mathematical Notations
Mathematics includes many symbols. For example, x2 means "x squared," and H2O is the formula for water.
Key Numbers:
Some numbers, such as π = 3.14, play a key role in calculations.
Application of Formulas:
For example, the formula for the area of a circle is A = πr2. Physical constants such as the speed of light in a vacuum are also important, and in chemistry, molecules with subscripts are common, such as CO2.
