| michael@0 | 10 | Description: |
| michael@0 | 11 | |
| michael@0 | 12 | The production AdditiveExpression : AdditiveExpression - |
| michael@0 | 13 | MultiplicativeExpression is evaluated as follows: |
| michael@0 | 14 | |
| michael@0 | 15 | 1. Evaluate AdditiveExpression. |
| michael@0 | 16 | 2. Call GetValue(Result(1)). |
| michael@0 | 17 | 3. Evaluate MultiplicativeExpression. |
| michael@0 | 18 | 4. Call GetValue(Result(3)). |
| michael@0 | 19 | 5. Call ToNumber(Result(2)). |
| michael@0 | 20 | 6. Call ToNumber(Result(4)). |
| michael@0 | 21 | 7. Apply the subtraction operation to Result(5) and Result(6). See the |
| michael@0 | 22 | discussion below (11.6.3). |
| michael@0 | 23 | 8. Return Result(7). |
