Since there are infinitely many real numbers between −1 and 3, we must express the solution graphically and/or with interval notation, in this case [− 1, 3). Example 6: Graph and give the interval notation equivalent: − 3 2 < x < 2 .... I get that both mean the same thing, but each of these programs would mark the other answer wrong (IE, if mathlab asks for interval notation and you put R, you get it wrong. if Hawkes asks for interval notation and you put (-inf,inf), you get it wrong).

Most students remember the infinity sign and the notation for all real numbers. Once I determine what they remember, I focus on what the students do not know or remember. I hand out the interval notation notes. Reading mathematics requires an understanding mathematical "shorthand." I always say that mathematicians do not like to write a lot, so they have symbols that make writing quicker... 2/10/2014 · Your question: "How do i write all real numbers except for 5 in interval notation?"

- (3) Let Y be the collection of all real numbers greater than or equal to 5 and strictly less than 10. Recalling notation from previous math courses, we may write: Y = [5;10)
- 15/09/2010 · Best Answer: (-infinity, infinity) (but you should use the infinity symbol, which looks like 8 on its side). This means all numbers bigger than negative infinity and smaller than infinity... and that's all real numbers!

- Though not as compact as interval notation, it is a way that mathematicians use to convey two important pieces of information: what types of numbers are included in the set (real numbers, integers, etc.), and which of those numbers are excluded from the set.
