Practice makes perfect
Let's start by solving the inequality.
1.1y < 4.4
DivIneq

.LHS /1.1.<.RHS /1.1.

y< 4

To solve this inequality using a calculator we begin by pressing Y=. Then, we write it on the first row. Notice that we will use x as our variable, as this is the only variable we are allowed to write using the calculator.
