Divergence: It denotes the flux density or outward flux of a vector field

Gradient: It denotes the direction in which the function changes most rapidly at a point

Curl: The vector used to measure the rate of rotation or circulation in a vector field is known as curl

Rank of a matrix: It is the number of non zero rows or columns in a row reduced matrix. It can be calculated either by reducing the matrix to row reduced form or by checking the value of the determinant of the main matrix and its minors.
