Can someone help me to expand the below equation for $N=2$ and $N=3$?

${f}_{i}=\sum \{{e}_{i}:j\le i\le k\}$ for some $1\le j\le k\le N$.

Here ${e}_{i}$ is the unit vector of coordinate i in an N-dimensional space.

Dealing with discrete Math is an interesting subject because discrete Math equations can be encountered basically anywhere from scheduling of sports games and live shows to education where each person is examined online. It is a reason why discrete math questions that we have collected for you are aimed at solutions that go beyond equations to provide you with the answers that will help you understand the concept. Still, discrete Math equations are explained as well by turning to problems in computer science, programming, software, and cryptography among other interesting subjects like software and mobile apps development.
