Today, we start with EQUATION.  Equation. A noun, in Mathematics,  

a statement that two expressions are equal. He's  starting to work out simple equations in school.  

It also means a complicated situation or issue.  And as we look at our real-life examples, we're  

going to see more of this use of equation. These  sentences have to do with complicated situations  

or issues, and sometimes with solving them.  Let's look again up close and in slow motion. 

And now we'll go to Youglish for five examples. So lifelong learning is I think a very,  

very important piece of the equation. Here, they're talking about a job  

crisis and what can be done in society to  keep as many people employed as possible.  

He's talking about this complicated issue, so in  this case, we're not talking about Math, but life.  

And he thinks lifelong learning, being willing  to learn new things when people lose their job,  

or their jobs no longer exist, is an  important part of solving that crisis. 

So lifelong learning is I think a very,  very important piece of the equation. 

Here's another example. So it really just changes  

the whole equation, you know? It changes the whole equation.  

Here, he's talking about corporate  income tax, and the problems with it,  

and how changing the laws in the  US can change the whole equation.  

The whole complicated situation of companies  booking their profits into low-tax countries.  

Again, we're not working out a Math problem, we're  looking at a complicated issue and discussing how  

changing pieces can change the whole equation. So it really just changes the whole  

equation, you know? Here's another example. 

It's only one piece of the whole equation. Just one piece of the whole equation.  

Just one part of a bigger, complicated issue.  It's only one piece of the whole equation. 

Another example. It's because I'm seeing  

an equation and they're dealing with exponents and  that 30 percent that I didn't know is showing up. 

Here, Sal Khan is talking about Math. He's talking  about the student experience learning Math.  

There's an equation with exponents. There's about  30 percent of this level of math that he doesn't know,  

doesn't understand, and that's what's on the test,  the part he doesn't know, so he starts to give up. 

It's because I'm seeing an equation and  they're dealing with exponents and that 30 percent 

that I didn't know is showing up. Our last example. 

So you see, your resume is  only part of the equation. 

Here, we're back to not talking about  Math, but talking about life. In this case,  

the issue of getting a job, a resume, is only  part of the equation. Other things matter,  

cover letter, how will you interview, what your  references have to say about you, for example. 

So you see, your resume is  only part of the equation. 

Our next word has two pronunciations, as a  noun, CONDUCT, as a verb, conduct.

Now, conduct, the way that a person  behaves in a particular place or situation.  

Eating while teaching is not considered to be  professional conduct. As a verb, conduct, second  

syllable stress now, to plan and do something.  I like the way the company conducts business.  

Let's look again up close and in slow motion. 

And now we'll go to Youglish for five examples. 

And so we have given them the green  light to go and conduct research studies. 

The green light, this means permission, a group of  people asked to do research on a particular topic,  

and their bosses looked at the situation and  decided it was a good idea, gave them permission,  

gave them the green light. If you use this  phrase, make sure you're using 'the' not 'a'  

it's not 'a green light' but to give the, the,  'the green light'. They got permission to conduct  

research, to plan, and do a research study. And so we have given them the green light to  

go and conduct research studies. Here's another example. 

We have to rethink the way we  conduct the public business. 

Conduct the public business. The  way we plan and do public business. 

We have to rethink the way we  conduct the public business. 

Here's another example. It's the words that you say,  

the way that you conduct yourself. The way that you conduct yourself. The way you  

do yourself, how you behave. Are you  positive, polite, do you show up to  

work on time? Are you trustworthy? Are you  always joking? How do you conduct yourself? 

It's the words that you say, the  way that you conduct yourself. 

Another example. You've held yourselves to a high code of conduct. 

A 'code of conduct' is a set of rules for how  to act. What is your code of conduct? For me,  

honesty is extremely important. I don't  want to lie or keep things from people. 

You've held yourselves to a high code of conduct. Our last example. 

But if they turn it over to student conduct,  then they will prosecute student conduct. 

So if you enroll in an American university,  you might need to sign a student code of  

conduct. It will state rules, expectations  on how you'll behave, like you won't cheat,  

you won't drink alcohol on campus, this kind  of thing. The rules will vary by university.  

Student conduct is an office that deals  with violations of the code of conduct.  

In this sample sentence, if someone cheats  in class, the professor might report that  

to student conduct. But if they turn it over  to student conduct, then they will prosecute. 

Our last word today is CONCLUSION.  Conclusion. Keep that first syllable  

really short. You don't need to try to put a  vowel in there. Con— con-- conclusion. A noun,  

a final decision or judgment, or the last  part of something. After thinking about it,  

we came to the conclusion that we shouldn't buy  the tickets. They're just too expensive. Let's  

look again up close and in slow motion.

And now we'll go to Youglish for five examples. 

So that brings us to your  conclusion, which I'm going to read. 

It looks like she's reading an article. The  conclusion is the last part of the article  

where you summarize what you've written, the  last thing you want the reader to think about. 

So that brings us to your  conclusion, which I'm going to read. 

Here's another example. That argument gives a wrong conclusion. 

Gives the wrong conclusion. This argument leads  you to the wrong decision, the wrong judgment. 

That argument gives a wrong conclusion. Here's another example. 

So the final conclusion is an optimistic one. The final conclusion. This is a little  

redundant. There's usually just one  conclusion, and it's the final decision. 

So the final conclusion is an optimistic one. Another example. 

You know, you're trying to, to  work towards, towards a conclusion. 

Work towards a conclusion. You want a  final decision or judgment to be made. 

You're trying to, to work  towards, towards a conclusion. 

Our last example. Alexander didn't reach that conclusion at all. 

Didn't reach that conclusion. They're talking  about a decision. This person, Alexander,  

had different ideas. Reached a different  decision than someone else, or a decision  

that was different from what was expected. Alexander didn't reach that conclusion at all.
