Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the fundamental operation?Multiplying a number or expression by itself
2. What is the mathematical notation?Expressed as x² or x2 in computing contexts
3. What does it mean to square a number?Squaring means multiplying a number by itself. For example, 7 squared is 7 × 7, which equals 49. We write it as 7².
4. Why is squaring called an even function?Because the result is the same whether you use a positive or negative number. For any x, x² equals (-x)². This symmetry makes the graph of x² look the same on both sides of the y‑axis.

Squaring: The algebraic operation of multiplying a number or expression by itself.
Perfect Square: A number that is the product of an integer multiplied by itself.
Quadratic: Pertaining to expressions or equations involving a variable raised to the second power.
Polynomial: An expression consisting of variables and coefficients, involving only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
