Equations: An equation in mathematics or physics is a statement that two expressions are equal. It is written using the equals sign (=). For example, 2+3=5 is an equation in mathematics, and F=ma is an equation in physics. Equations also describe the laws of nature. The reason is that causes and effects do not occur in equations. See also Causes, Effects, Natural laws._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
