| * multiplicativeExpression (additiveOperator multiplicativeExpression)* | |
| * super (additiveOperator multiplicativeExpression)+ |
| * ; |
| * additiveOperator: |
| * '+' | |
| * '-' |

| * An additive expression is either a multiplicative expression, or an |
| * invocation of an additive operator on either super or an expression e1, with |
| * argument e2. |
| * @description Checks that an additive expression of the form |
| * multiplicativeExpression ('+' multiplicativeExpression)* |
