GeoGebra
To start, you should familiarize yourself with the following symbols and terms:
-
Addition:
+ -
Subtraction:
- -
Multiplication:
*orspace -
Division:
/or: -
Exponents:
^+ <Exponent> -
Square root:
sqrt(<Number>) -
th roots:
nroot(<Number>, <n>) -
An exact/symbolic value is a value given as a fraction or a root, with
before it. An exact value can also be an integer. -
A numeric value is a value given by a rounded decimal number, with
before it.
Example 1
To compute , type 2. ^3
To compute , type sqrt(4).
To compute , type nroot(27, 3).
To compute , type 8-7(2. ^2-3/4)
Example 2
To enter fractions in GeoGebra, use “/” or “:”. For example, is entered as 2/3.
If you have several terms or factors in the fraction, you must use parentheses around the numerator and the denominator. For example, to compute , type
2/(5*3) or 2/(5 3)
If you type
2/5 * 3 or 2/5 3
then you get
