how do you find the interval

Interval between what and what? Since I am not sure what you are asking, I searched Google under the key words "find interval" and "find interval math" to get these possible sources:

I hope this helps. Thanks for asking.

To find an interval in mathematics, you need to know the starting and ending points of the interval.

For example, if you wanted to find the interval between two numbers, such as 0 and 10, you would simply subtract the smaller number from the larger number:

Interval = Larger Number - Smaller Number
Interval = 10 - 0
Interval = 10

So the interval between 0 and 10 is 10.

However, it's important to note that intervals can be defined in different ways depending on the context. In mathematics, an interval can also refer to a connected subset of the real numbers. For example, the interval [0, 10] represents all real numbers between 0 and 10, including 0 and 10 themselves.

To determine the interval between two points in a wider mathematical context, you would need to specify the type of interval you are referring to.
