| Addition and subtraction : | |
| 1 + 1 = 2 | |
| 2 - 1 = 1 | |
| Multiplication, division, and modulus : | |
| 5 % 2 = 1 | |
| 5 % 0 = $rem2 | |
| 7 % 2 = 1 | |
| 5 / 2 = 2 | |
| 5 / 0 = $rem4 | |
| 5 * 2 = 10 | |
| 5 * -1 = -5 | |
| 5 * -2 = -10 | |
| 5 * -2 = -10 | |
| And now null nodes to make sure it doesn't throw an NPE : | |
