# How to Decrease Mistakes in Algebra – Part 2

Algebra is an area of math that leads many students to make mistakes. Using a simple “Double-Slash” mark helps students wall off parts of algebra expressions from other parts, so that they avoid making mistakes. This post and the next several post will help educators learn how to use the “Double-Slash.”

# How to Decrease Algebraic Mistakes – Part 1

Algebraic expressions are covered with mental “land mines.” Step the wrong way, and an expression will blow up on the page, making it impossible for students to move in the right direction. Fortunately there’s a simple thing students can do to succeed at simplifying algebraic expressions, and that simple something is using what I call the “Double-Slash.” This is the first in several blog posts that show educators how to use the “Double-Slash” as part of their everyday algebra instruction.
