What is Algebra?

Algebra is a part of math that focuses on using letters and symbols to represent numbers and the rules for working with them.

Why is Algebra important?

Algebra acts as a common link in nearly all areas of mathematics and is essential for higher education in subjects like math, science, engineering, and economics.

What are Variables in Algebra?

Variables are placeholders that can hold different values, helping to create formulas and rules in various situations.

What are Pronumerals?

Pronumerals are terms written in alphabetical order, such as 5xy.

Coefficients are numbers in front of variables, such as the 3 in 3t.

What are Expressions in Algebra?

Expressions consist of variables, numbers, and operations, but do not include an equality sign (=).
