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

 

π 2

 

 

5 + 2 (5 +

3

2

)

 

 

 

 

 

 

First, we need to highlight the entire first term by using either the right arrow () or the upper arrow () keys, repeatedly, until the entire expression is highlighted, i.e., seven times, producing:

NOTE: Alternatively, from the original position of the cursor (to the right of the 2 in the denominator of π 2/2), we can use the keystroke combination ‚— , interpreted as (‚‘).

Once the expression is highlighted as shown above, type +1/3to add the fraction 1/3. Resulting in:
