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.
