Unit 2: Solving Equations
Lesson 2.5: What are Formulas and How Can We Use Them?
Can you rearrange an equation successfully?
Can you get comfortable keeping an equation balanced?
A formula or literal equation is an equation that is proven to be true in our universe.
Here are some common formulas you have probably used:
The history of mankind has altered when we discover a new formula. Pythagoras discovered formulas to describe measurements and physical space. Isaac Newton discovered formulas to describe our motion and gravity. Albert Einstein discovered the connection between pure energy and the matter of which we are made.
Equations are a most useful tool - they are how can how see if something works or doesn't work. They are the lifeblood of algebra and all mathematics. Formulas describe all sorts of things that are important to you and your world (whatever that may be).
Perhaps you will one day discover a new formula to better humankind.
Let's look at the very useful 'Temperature' formula, listed last on the table above. Can you solve that for F? What steps do you need to do first in order to solve for F and still maintain the structure of the formula?
