<p>In Economic Principles and Intermediate Microeconomics?</p>
<p>For economic principles I and II, very simple math. As long as you know some simple algebra and can interpret curves (slopes, tangents, intersections), you'll be fine. I'm not sure about inter. however but i do know it requires calculus as a prereq so it probably will take use of some tools learned in calc 1.</p>
<p>for intermediate macro, calc is a prereq, and it helps if you can do partial differentiation (differentiate a function in respect to one variable, treating other variables as constants). Other than that, it requires very simple math; calculator's aren't even necessary for exams.</p>
