Basic Usage

This notebook demonstrates the basic usage of the Calculator package.

The basic arithmetic operations are contained in the Calculator class.

[1]:

from calculator import Calculator

[2]:

calc = Calculator()

The subsequent sections operate on two numbers \(a\) and \(b\).

[3]:

a = 5
b = 3

Addition

The addition operation add both numbers a and b

\(\Large c = a + b\)

[4]:

c = calc.add(a, b)

[5]:

print(f"The result of the addition is {c}.")

The result of the addition is 8.

Subtraction

The subtraction operation subtracts number \(b\) from number \(a\)

\(\Large c = a - b\)

[6]:

c = calc.subtract(a, b)

[7]:

print(f"The result of the subtraction is {c}.")

The result of the subtraction is 2.

Multiplication

The multiplication operation multiplies the fatctors \(a\) and \(b\)

\(\Large c = a \cdot b\)

[8]:

c = calc.multiply(a, b)

[9]:

print(f"The result of the multiplication is {c}.")

The result of the multiplication is 15.

Division

The division operation divides \(a\) by \(b\)

\(\Large c = \frac{a}{b}\)

[10]:

c = calc.divide(a, b)

[11]:

print(f"The result of the division is approximately {c:.3f}.")

The result of the division is approximately 1.667.

Note: You must not divide by \(0\).

[12]:

c = calc.divide(a, 0)
