In this section, two types of calculators will be introduced. Instructions on inputting fractions, exponents and radicals will be discussed.
Type1: 
To input a mixed fraction, press [integer] - - [numerator] - - [denominator]
Example1 : 2\(\frac{3}{4}\)
2 - - 3 - - 4
Example2 : \(\frac{42+21}{1-23}\)
- 42 - 
- 21 - 
- - - 1 - 
- 23 -
Type 2: 
To input a fraction, press [numerator] - 
- [denominator]
Example1 : \(\frac{3}{4}\)
3 - - 4
To input a mixed fraction, press [integer] - 
- - [numerator] - 
(down) - [denominator]
Example2 : 2\(\frac{3}{4}\)
2 - - - 3 - - 4
Example3 : \(\frac{42+21}{1-23}\)
- 42 - 
- 21 - - 1 - 
- 23
Type 1: 
To input an exponent, press [base] - 
- [power]
Example : \( 2^3 \)
2 - - 3
Type 2: 
To input an exponent, press [base] - 
- [power]
Example : \( 2^3 \)
2 - - 3
Type 1:
or
To input a square root, press - [value in the square root]
Example1 : \(\sqrt{100} \)
- 100
To input a cube root, press 
- - [value in the cube root]
Example2 : \(\sqrt[3]{100} \)
- - 100
To input any radicals, press [degree of the root] - - - [value in the radical symbol]
Example3 : \(\sqrt[4]{100} \)
4 - - - 100
Type 1:
