Pro Tip 1/3Not Just Numbers
Algebra uses symbols, often letters, to stand in for unknown numbers in equations.
Find the value of 'x' in the equation x + 5 = 9.
Pro Tip 2/3Problem Solving
Algebra is often about finding the missing numbers that make an equation true.
If 3a = 9, what does 'a' equal?
Pro Tip 3/3Real-World Use
Used for calculating things in real life, like expenses, distances, or time.
Price of 5 apples (a) is $10: 5a = 10.

They're a little edgier than that. But then the comments got a little more intense, student after student saying that they had grown up not liking math. It was getting difficult as they got into more advanced math topics. By the time they got to algebra, they had so many gaps in their knowledge they couldn't engage with it.

I have linear algebra, science, physics -- even, nowadays, chemistry and biology, as you've seen. These are all the tools we need. So the more tools you have, for Batman, more effective at fighting the bad guys, for us, more tools to attack these kinds of big problems. So education is very important.

So we can demonstrate that this is true using probability and algebra to calculate the average number of flips it would take to get each combination. Let’s start with the heads/tails board, and define x to be the average number of flips to advance one step.

I know we can all remember the days of sitting in algebra class asking ourselves, 'why will I need algebra or chemistry in the future?' The answer was and still remains that advanced math and science classes help high school students develop their analytical and cognitive skills and better prepare them to compete in college and the workplace.

Daniel Goldstein
American Psychologist
Psychology, unlike chemistry, unlike algebra, unlike literature, is an owner's manual for your own mind. It's a guide to life. What could be more important than grounding young people in the scientific information that they need to live happy, healthy, productive lives? To have good relationships?
