# Is the following true of false?

Math is my worst damn subject, here goes is -16<11? True or false? Next question someody please explain 'overlapping intervals' and how in the hell am I suppose to graph them. Examples would be great.

-16 < 11 is true. Any negative number is always less than a positive number. Imagine a number line with negatives to the left of zero and positives to the right..that should help you out.

good luck! :)

true...

Any negative number is less than any positive number. Owing money is always less than having money.

Overlapping intervals means sections of the graph that include one another. Think of overlapping shingles on a roof. You didn't specify what math you're in, a quick search on "overlapping intervals" turned up topics in statistics, calculus, and information processing. But since you're having trouble with -16 < 11 I'll make an assumption that you're in basic algebra and explain it in those terms.

Here, overlapping intervals would be intervals such as (3,5) and (4,6). To graph them on a number line you'd do something like this:

<------0 --- 1 --- 2 --- (3 --- (4 --- 5) --- 6) --- 7 --- 8 --->

(

Sorry this isn't very good but there's only so much can be done on tihs online text editor.)

To understand overlapping intervals in everyday life, think of "the semester:" (late aug thru early december) and "the holiday season" (late nove thru Jan 2). Those are overlapping intevals because they include one another.

The opposite would be non-overlapping intervals or partitions. An everyday example of this would be the months of the year. Each day of the year is a member of exactly one month, it's never part of two different months.

If none of what you're seeing here is answering your questn, you need to define your question better, tell what math you're in where you're encountering "overlapping intervals". Then maybe someone can help you better.

And please watch your language. The math gods appreciate appreciation, and the Yahoo gods haev been known to delete messages that contain profanity.

Keeping a number line in mind:

For -16 < 11, read as "-16 is (left of) 11" on the number line.

Ex. 4 > 1, "4 is (right of) 1" on a # line.

Overlapping intervals: Ex. [-3, 0] & [-2, 3] overlap on a # line.

Best way to understand negative versus positive numbers is via a line graph.

<----smaller larger--->

Overlapping interval is any interval that has equal members.

An interval (-50 to -10) and (-20 to 0) are overlapping in the section of (-20 to -10) because this section is contained in both intervals. Draw in out in a line graph

It's true, -16 is less than 11.

First of all, the symbol < means LESS THAN.

The symbol > means GREATER THAN.

Secondly, BOTH symbols are called inequality symbols or notations.

Negative numbers are ALWAYS smaller than positive numbers.

You have -16 read "NEGATIVE 16" and you also have 11 read "POSITIVE 11."

Positive is BIGGER than negative.

11 is BIGGER than -16.

NOTE: The arrow points to the smaller number REGARDLESS of direction. Is this clear?

It is true because 16 is a negative number. The negative numbers are always smaller than the positive numbers.
