>[!summary] An even number is a number that be written in the form $n = 2k$ An odd number is a number that be written in the form $n = 2k +1$ Where k represents an integer >[!info]+ Read Time ⏱ **1 min** # Definition An integer is said to be even if it is a multiple of 2. That is if we rewrite the $n$ as $n = 2k$ where k represent an integer. We also represent even number if we can divide n by 2. Such we get an integer if after we compute $n/2$ An integer is said to be odd, if it has exactly 1 more than a multiple of 2. That is if we rewrite $n$ such that $n = 2k +1$ where k represents an integer. # Resources <iframe width="560" height="315" src="https://www.youtube.com/embed/TQZh9yvxFSY?si=KlCF4e3I9EMunXpi" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> --- 📂 Want to see more structured notes like these?
