Let
represents the age at which a person gets a student learner's permit to drive in New Jersey.
Also, an individual must be at least
years old to get a student learner's permit to drive in New Jersey.
So, inequality is 
(Inequality explains a relationship of greater than or greater than or equal to or less than, or less than or equal to between two mathematical expressions)
In three dimensions, the cross product of two vectors is defined as shown below

Then, solving the determinant

In our case,

Where we used the formula for AxB to calculate ixj.
Finally,

Thus, (i+j)x(ixj)=i-j
