# How do Conditional Blocks Work
Let’s consider an example to understand how conditional blocks filter users when different logical operators such as `AND`, `OR`, and `NOT` are applied. Suppose, you want to filter male users who have performed both the `pageView` and `checkout` events within the last 10 days. We can build this scenario in Audience using three conditional blocks (conditional block `A`, `B` and `C`) as shown in the images below. Note that we are using AND operator between the conditional blocks for this particular use case, `((A AND B) AND C)`.
**Conditional Block A: Filters users by Gender** `Male`
**Conditional Block B: Filters users who have performed** `pageView` **in the last 10 days**
**Conditional Block C: Filters users who have performed** `checkout` **in the last 10 days**
Now that we have built the conditional blocks, let us understand how the users qualify for these conditions. Consider four users who have performed the following events:
* User 1 – A male who has performed both the `pageView` and `checkout` events in the last 10 days.
* User 2 – A female who has performed only the `pageView` event in the last 10 days.
* User 3 – A male who has performed both the `pageView` and `checkout` events in the last 10 days.
* User 4 – A female who has performed both the `pageView` and `checkout` events in the last 10 days.
**Result**
Based on the above conditional blocks, `User 1` and `User 3` qualify. Applying the `AND` operator between the conditional blocks, we obtain a subset of users who are male and have performed both the `pageView` and `checkout` events in the last 10 days.
