An interval as a set of numbers. Numbers = endpoints.
Build interval notation
We get interval notation by saying 3s<60
Since our variable of s has a coefficient of 3 Divide each side of the inequality by 3
3s
3
<
60
3
s<20 ←Use this expression going forward
Inequality Sign Evaluation
You entered the < sign
Build the interval notation for s:
No equal sign translates to ). Do not include the number 20
Based on the < you entered, the left side of the interval notation will extend to negative infinity, which is denoted as -∞

(-∞,20)
You have 2 free calculationss remaining
Set Builder Notation for s:
{ s | s<20 } where | denotes such that
Display the literal notation for s
∞,...,10,11,12,13,14,15,16,17,18,19
What is the Answer?
(-∞,20)
How does the Interval Notation and Set Builder Notation Calculator work?
Free Interval Notation and Set Builder Notation Calculator - This calculator translates the following inequality statements to interval notation and set builder notation:
* x < 5
* y <= 5
* z > 5
* a >= 5
* b < 5 or b > 20
* Compound Inequality such as 0 <= c < 4
* |x|<3
* Reverse Interval Notation to Inequality Statement such as (-7,5]
* {x|x<1}
* Word representations of interval notations such as 2 is less than or equal to x is less than or equal to 8 This calculator has 2 inputs.
