Types of Equations
The HP 35s 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.
