# Math help from the Learning Centre

This guide provides useful resources for a wide variety of math topics. It is targeted at students enrolled in a math course or any other Centennial course that requires math knowledge and skills.

## How to use a scientific calculator

In this section, two types of calculators will be introduced. Instructions on inputting fractions, exponents and radicals will be discussed.

## Fractions

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

## Exponents

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: 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
