What is is an equation?

Answer 1

An analogous equation is one that can be applied to different components with the change of component symbol eg if A has been subscripted but now your looking at it wrt to B then it will switch places in the subscript.

Answer 2

An equation in mathematics is an expression which sets one quantity equal to another.

An example is 3y + 2x = 7.

In chemistry it is a summary of what happens in a reaction. It may be written in words or symbols. If it is symbols, each substance is represented by its chemical formula, and it is balanced to show how much of each substance is involved.

Answer 3

The equator is an imaginary line that divides the Earth into the Northern Hemisphere and Southern Hemisphere. Its length is about 24,901.5 miles (40,075 kilometers). The line crosses the continents of South America and Africa, as well as a number of islands, and runs through 14 countries, including Ecuador, Columbia, Brazil, Gabon, São Tomé and Príncipe, Congo, Zaire, Uganda, Kenya, Somalia, and Indonesia. The location of this imaginary line is indicated in many areas, making it possible to stand with a foot in each hemisphere. The geographical areas surrounding it are known as the equatorial regions, and they have a particular type of climate.

Answer 4

In mathematics, an equation is an expression which states that two stated quantities are equal, by writing the two expressions separated by an equals sign, from which a person is to determine one quantity from another.

Answer 5

A statement that two expressions are equal, for example:4 = 4

1 + 2 = 10

While the second statement is not true, it is still an equation. An equation may also have a variable:

x = 5

2x + 3 = 15

Answer 6

In Mathematics, a statement that the values of two mathematical expressions are equal.

Answer 7

An equator is an imaginary line around the centre of a sphere or celestial body, dividing it into two halves.
