These so-called MicroDYN items are high quality and designed to assess individual problem solving skills. The items are based on linear structural equations. We describe how this approach was applied to create an assessment item for a collaborative setting with children that implements a simplified ...

Not all equations can be solved mentally. We now wish to introduce an idea that is a step toward an orderly process for solving equations. Is x = 3 a solution of x - 1 = 2? Is x = 3 a solution of 2x + I = 7? What can be said about the equations x - 1 = 2 and 2x +...
Elimination Method for Solving Systems of Linear Equations:The elimination method is commonly used to solve systems of linear equations. In this approach, we add the two equations together ensuring that one of the variables cancels the other out during the summation. This resul...
2. When solving a trigonometric equation involving more than one trig function, do we always want to try to rewrite the equation so it is expressed in terms of one trigonometric function? Why or why not? 3. When solving linear trig equations in terms of only sine or cosine, how do we ...
As we want to sum it up over all i,j,a,bi,j,a,b such that a+2j=na+2j=n and b+2i=mb+2i=m, we can keep track of these equations with two formal variables xx and yy. Then, the sum that we're interested in expresses as [xnym]∑i,j,a,b(i+ji)2(a+ba)x2j+ay2i...
