Hey what's up? Good to see everyone. Recently some people asked me,  'How do you add
integers? What do you do there? I know
there's many different approaches and I'm going
to show you one approach called the 'war'
approach. Why do they call that? Let me
show you.  This is our first example: -5 +3.
Now -5, we've got 1, 2, 3, 4, 5 negatives, right?
Now I've got postive 3. 1, 2, 3 positives, right? Now what happens?The war.
These two shoot each other, shoot each other and now they're eliminated. Who wins, who wins the war?
Minuses win.
-2: that's your answer. And we're
done! Okay another example: -10 + 6.  -10
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 negatives, right? Now
Now + 6. 1, 2, 3, 4, 5, 6 right? Now they have the war. Shoot each other, shoot each other
all of these guys shoot each other all of them, all these guys shoot each other and what do we have left?
Who wins the war? -4. Four negatives left.
And we're finished.
In our third example here:
-8 +12
Next positive12...
Now the war: Shoot each other, shoot each other, shoe each other, all these guys shoot each other.
Who wins? Positive 4.
Thank you for watching. See you later!
