Remind students to match types on both sides of the equations because they often try to combine types when creating variables.

Ints need to be equal to ints, and doubles to doubles.

A common error occurs when students try to set an int equal to a string.

For example, int num = "2.5";

This stems from not fully understanding that the type on the left of an equation has to equal the type on the right of the equation.
