Time for the first level with an actual logic gate. This level asks you to figure out the behavior of the NAND gate.
| Input One | Input Two | Output |
|---|---|---|
| No | No | Yes |
| No | Yes | Yes |
| Yes | No | Yes |
| Yes | Yes | No |
As the truth table shows, a NAND gate returns true unless both inputs are true, then it returns false. so set the result accordingly and press the verify button.
