Interval notation is a simplified way of describing a particular interval. Let’s see how it’s done. 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 u...
The members of these two sequences have some interesting properties. Whenever youaddtwo even integers together, or two odd integers together, the answer is always an even number. For example, 2 + 6 = 8, 1 + 5 = 6, or 11 + 17 = 28—always even! However, whenever you add one even...
“Being a math major is like being an artist, using your mind to visualize abstract concepts and fitting them together to get the final piece. This final piece might even lead to more questions that you could potentially research on in the future. To anyone considering math, you are always ...
