Independent variable is the variable that you change in an experiment.
The symbols for integers (not the set of integers) are often the letters n, i, j and k. In some early programming languages, any variable whose name started with the letters i to n (inclusive) was an integer variable.
a standardizing variable is a variable that has a mean of zero and a standard deviation of one .
any letter can be a variable
k = you - int (you / j) * j; You can also use, if your language supports the modulus (%) operator... k = you % j;
5+j=6. Now there is
a variable??

In the simplex method, ( z_j - c_j ) represents the reduced cost of a non-basic variable ( j ). Here, ( z_j ) is the contribution of variable ( j ) to the objective function value based on the current solution, while ( c_j ) is the cost coefficient of that variable. If ( z_j - c_j ) is positive, it indicates that increasing variable ( j ) would not improve the objective function, while a negative value suggests that increasing ( j ) could be beneficial for optimization.
