HiSet: High School Equivalency Test: Math

The HiSet Math subject prepares students for the mathematics section of the High School Equivalency Test, covering essential math skills and concepts.

Basic Concepts

Algebraic Thinking

What is Algebra?

Algebra is about finding the unknown! You use letters (like \( x \) or \( y \)) to represent numbers you don't know yet. Algebra helps you solve puzzles, figure out patterns, and predict results.

Solving Equations

When you see something like \( x + 5 = 12 \), your job is to find the value of \( x \) that makes the equation true. You “undo” operations to isolate the variable.

Using Algebra in Life

From figuring out how many hours you need to work to reach a savings goal, to understanding cell phone plans, algebra pops up everywhere.

Common Steps

  • Combine like terms.
  • Use the same operation on both sides to keep things balanced.

Examples

  • Finding how many more points you need to win a game if you already have 18 and need 25.

  • Solving \( 2x = 10 \) to find out how many tickets each person gets if 10 tickets are split evenly.

In a Nutshell

Algebra helps you solve for unknowns and understand patterns in life.

Key Terms
