worksheet. Other objects (including text objects) are added after the highlighted object. To
insert a text object above the square root of 24, first highlight the object that is now above it.
Highlight expression #3.
Display a function description of the
Insert Text
button
by moving the mouse pointer
onto it.
Insert a text object by clicking on the
Insert Text
button
.
Highlighting of a text object is indicated by a frame around it. The blinking cursor inside
indicates text editing mode.
Enter the text:
We compute the square root of 24:
A text object allows simple text editing similar to what you can do in standard text editors. Later
you will learn how to change the font size, alignment, color, etc.
As a next example compute
56
1234
. Due to the previous activity, the focus now is in the algebra
window. Before you can enter another expression, move the focus into the entry line.
Enter
1234^56
by using the

button
, then typing the respective string
of digits followed by
(¢)
. The exponentiation operator ^ can be found on both the
keyboard and the Math Symbol Toolbar. (It is the sixth symbol from the left in the first row.)
Simplify using
.
This is a very big number. For those who want to know the number of digits, there are two
methods to find out: First, you can count them. Second, you can approximate the number.
