Hi, my name is Marija, I'm a mathematician, and today I'm gonna tell you what a quadrant means in math. And a quadrant, if you look at the prefix, you might know that quad means four. So a quadrant is one fourth of a coordinate plane, what I mean by coordinate plane, is simply a graph. So, we're gonna draw an x and y axis, here's my x-axis and here's my y-axis, and this is my coordinate plane, right? And I have all my positive numbers along the x-axis here, 1,2,3,4 and on, and my negatives on this side. And then with the y-axis, I have my positive numbers up here, and I have my negatives down here. And the quadrants are gonna be the four pieces that you see this graph is split up into. And quadrants are named in Roman numerals. And we start with quadrant I in the upper right-hand corner. So this is quadrant I. And then we're gonna go ahead and move counter-clockwise to get to quadrant number II. This is quadrant number III. And this would be quadrant number IV. So quad, again you can remember it because quad indicates four, it's the four equal parts of a coordinate plane or a graph. And you have to remember that their written in Roman numerals, and they begin in the upper right-hand corner. So quadrant I contains all positive numbers, all positive values, because the x's and y's are both positive in quadrant I. Then you have quadrant II, III and IV, moving counter-clockwise. My name is Marija, and I just showed you what a quadrant means in math.
