Explanation Approach: If A = [ a i j ] is a m × n matrix and B = [ b i j ] is a n × p matrix, then the product A B is an m × p matrix given by A B = [ c i j ] . Here, c i j = a i 1 b 1 j + a i 2 b 2 j + … + a i n b n j . Calculation: Consider, A B = [ 0 4 − 3 2 1 7 3 − 2 1 ] [ − 2 0 0 − 4 1 2 ] = [ ( 0 × − 2 ) + ( 4 × 0 ) + ( − 3 × 1 ) <

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
