A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. It is commonly used in mathematics and computer science to represent and manipulate data.
A matrix is typically written inside a set of square brackets [] with the elements separated by commas. For the given information, the matrix would be written as [x] = [-10].
In this context, x is a variable and -10 is its value. This means that the only element in the matrix is -10 and it is located at the intersection of the first row and first column.
Yes, a matrix can have any number of rows and columns as long as the number of elements in each row is equal to the number of elements in each column. For example, a 2x3 matrix has 2 rows and 3 columns.
Matrices are commonly used in science to represent and analyze data, especially in fields such as physics, chemistry, and biology. They are also used in computer science for data storage and manipulation, and in statistics for data analysis and modeling.
