Quick Start

Get started with the expression calculator by typing mathematical expressions directly. Here are some basic operations:

Basic Arithmetic

2 + 3                   # Addition 5
10 - 4                  # Subtraction 6
5 * 6                   # Multiplication 30
15 / 3                  # Division 5
2 ^ 8                   # Power 256
10 % 3                  # Modulus 1
5!                      # Factorial 120

Using Functions

sqrt(16)                # Square root 4
sin(pi / 2)             # Sine 1
cos(0)                  # Cosine 1
log(100, 10)            # Logarithm 2
abs(-5)                 # Absolute value 5
round(3.7)              # Rounding 4

Constants

pi                      # 3.141592653589793
e                       # 2.718281828459045
tau                     # 6.283185307179586
phi                     # 1.618033988749895

Variables

x = 10                  # Assign variable
y = 5
x + y                   # 15
x * y                   # 50

Complex Numbers

2 + 3i                  # Complex number 2 + 3i
(1 + 2i) * (3 - i)      # Complex multiplication 5 + 5i
sqrt(-1)                # i

Units

5 cm + 2 inch           # Unit addition 10.08 cm
90 km/h to m/s          # Unit conversion 25 m/s
5 kg * 9.8 m/s^2        # 49 N

Matrices

[1, 2, 3]               # Vector [1, 2, 3]
[1, 2; 3, 4]            # 2x2 Matrix [[1, 2], [3, 4]]
