Addition

Addition combines two numbers into a total sum.

\( a + b \)

Multiplication is repeated addition of a number.

\( a \times b \)

The square root of a number is a value that, when multiplied by itself, gives the original number.

\( \sqrt{x} \)

Factorial is the product of all positive integers up to a number.

\( n! = n \times (n-1) \times \dots \times 1 \)

Used to solve equations of the form \( ax^2 + bx + c = 0 \).

\( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)

Relates the sides of a right triangle.

\( a^2 + b^2 = c^2 \)

Mathematics is the study of numbers, patterns, and logical relationships.

Examples of expressions:

\( \int x^2 dx = \frac{x^3}{3} + C \)
\( e^{i\pi} + 1 = 0 \)
