Give the logic symbol of NAND gate.

Explanation

To derive the logic symbol of a NAND gate, we can follow these steps:

### Step 1: Understand the Basic Gates
The NAND gate is a combination of an AND gate followed by a NOT gate.

### Step 2: Draw the AND Gate Symbol
The symbol for an AND gate consists of a flat-ended shape with two inputs on the left and one output on the right. The inputs are usually labeled as A and B.
