Types of Equations
The HP 32SII works with three types of equations:
Equalities. The equation contains an "=" and the left side contains
more than just a single variable. For example, x 2 + y 2 = r 2 is an equality.
Assignments. The equation contains an "=" and the left side contains
just a single variable. For example, A = 0.5 × b × h is an assignment.
