Answer :
The 4 types of algebra are Elementary Algebra, Linear Algebra, Abstract Algebra, Boolean Algebra.
1. Elementary Algebra - This type of algebra deals with basic operations such as addition, subtraction, multiplication, and division. An example of elementary algebra is solving for x in the equation 2x + 3 = 7. In this equation, the variable x has a value of 4.
2. Linear Algebra - This type of algebra deals with linear equations and linear transformation. An example of linear algebra is solving for the vector x in the equation Ax = b, where A is a matrix and b is a vector.
3. Abstract Algebra - This type of algebra deals with abstract concepts such as groups, rings, and fields. An example of abstract algebra is finding the inverse of a matrix A. The inverse of A can be found by solving the equation A x A-1 = I, where I is the identity matrix.
4. Boolean Algebra - This type of algebra deals with logical operations such as OR, AND, NOT, and XOR. An example of Boolean algebra is finding the logical complement of a statement P. The logical complement of P can be found by solving the equation P OR NOT P = TRUE.
