Figure 6-15: Two ways to implement the inequality x ≥ 10

The examples provided in Table 6-9 demonstrate how to use Scratch’s
relational and logical operators to express inequalities that contain the ≥
and the ≤ operators.

We’ve explored several Scratch concepts in this chapter so far, includ-
ing comparisons, conditional statements, and logical operators. Now, let’s
use that knowledge to create some fun and useful applications.
