An interval as a set of numbers. Numbers = endpoints.
Build interval notation
We get interval notation by saying 4b<20
Since our variable of b has a coefficient of 4 Divide each side of the inequality by 4
4b
4
<
20
4
b<5 ←Use this expression going forward
Inequality Sign Evaluation
You entered the < sign
Build the interval notation for b:
No equal sign translates to ). Do not include the number 5
Based on the < you entered, the left side of the interval notation will extend to negative infinity, which is denoted as -∞

Set Builder Notation for b:
{ b | b<5 } where | denotes such that
Display the literal notation for b
∞,...,-5,-4,-3,-2,-1,0,1,2,3,4
What is the Answer?
(-∞,5)
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.
