 ====Slope====
 To get a more visualized understanding of rate of change, we can think of slope as the simplest case of rate of change:
 <center>
-$rate\, of\, change\,=\frac{change\, in\,ychange\,in x}\),</center>
+$rate\, of\, change\,=\frac{change\, in\, y}{change\, in\, x\,}$
 which is the slope of the line located by the two data points. Zero rate of change will be illustrated with a horizontal line.

 ===Overview===
 Rate of change is a simple technical analysis indicator describing the rate in which one quantity changes in relation to another quantity:
-<center>\(rate of change=\frac{change in y}{change in x}\)</center>
+<center>
 The rate of change can be positive or negative indicating an increase or decrease in y between two data points when x increases by a unit. When a quantity does not change over time, it implies a zero rate of change. Momentum is the absolute difference between two data points, which will correspond to the change in y. Here, we introduce the concept of rate of change and show application of rate of change in technical analysis.
