**Nickzom Calculator**is a free calculation-based application empire created by Idoko Nicholas Chinazom that helps one to carry out his or her simple or difficult calculations on Mathematics, Physics, Engineering and Switches based on its available contents and at the same time lays out the solution(s) and steps for quick and easy understanding. The goal of this app is to provide one with solutions and steps to his or her calculations available within the app's contents and any problem one faces.

Below are the present topics in Nickzom Calculator, more are to be added over time.

**Engineering**, Nickzom Calculator covers:

• Economics

• Basic Electrical

• Basic Electronics

• Calculus

• Laplace Transform

• Linear Algebra

• Linear Programming

• Mechanics

• Ordinary Differential Equation

There are so many other sub topics in this major topics. For Example in Linear Algebra, Nickzom can calculate Matrix Arithmetic, Inverse of a Matrix, Determinant of a Matrix, Transpose of a matrix, Adjoint of a matrix, Minors and Cofactors of a matrix. It can also solve simultaneous equation using matrix method. Not only that in matrix arithmetic, one can perform any of this operation: Addition and Subtraction of a matrix, Multiplication of matrices, Multiplication of a matrix by a scalar, Division of a matrix.
