HP 50g manual + 2 ⋅ 5 +

Suppose that you want to replace the quantity between parentheses in the

denominator (i.e., 5+1/3) with (5+π2/2). First, we use the delete key (ƒ) delete the current 1/3 expression, and then we replace that fraction

with π2/2, as follows:

ƒƒƒ„ìQ2

When hit this point the screen looks as follows:

In order to insert the denominator 2 in the expression, we need to highlight

the entire π2 expression. We do this by pressing the right arrow key (™) once. At that point, we enter the following keystrokes:

/2

The expression now looks as follows:

Suppose that now you want to add the fraction 1/3 to this entire expression, i.e., you want to enter the expression:

5+ 1
