Pre-algebra
If the student is taking this branch of mathematics, they are expected to show their work because they're expected to solve specific problems in a certain way. Ex, when they're solving for a variable they're supposed to manually find the value of x by isolating it rather than entering the left and right hand of the equal sign in the calculator (in slope-intersect form) and finding the intersection point. If they only get the correct answer without showing work, we give them 2 points. 8 more points if work is shown.
Algebra
Students in algebra are expected to know how to get the correct answer. We don't care how they do it, as long as it's the correct answer.
