Dirac or “bra-ket” notation is commonly used in quantum mechanics and quantum computing. The state of a qubit is enclosed in the right half of an angled bracket, called the “ket”. A qubit, \(\lvert \Psi \rangle \), could be in a \(\lvert 0 \rangle \) or \(\lvert 1\...

Step 1: We write the first and last number of the interval, which are the endpoints of the interval. For example, if the interval is from 6 to 20, we write 6, 20. Step 2: We use a round or square bracket on each side of the two numbers. We use:...
