Solving Equations
We will be using very simple math throughout the year. This will mostly be arithmetic, diving and multiplying numbers. We will also solve a few very simple equations, like or. Without concerning ourselves with the meaning of the symbols, we should be able to solve these equations for a variable other than F or v.
Solve F= ma for a:
Please not that every time I change the equation I use a new line and all of the equal signs are lined up You could also have. flipped the equation around in the beginning. 
Often you will want to write this:
.
Here all the operations are written into one line and although I can guess as to what you are trying to do, it doesn’t make much sense and in most cases will be wrong.

here is a simple trick that might help you solve these equations. Write the equation, for instance , into a triangle. You will see how the equation shows up inside this triangle by looking at the two ovals.
You will see how the equation shows up inside this triangle by looking at the two ovals.
If you want to solve for d = vDt, the triangle read like this:
Solving for Dt which will lead can also be accomplished with his triangle as you can see on the left.

This might all seem too easy to worry about, but when we are solving problems in class on tests or on the exam, not being able to solve such equations is the source for most of the errors I will have to correct.
