We're adding and subtracting numbers.

But adding and subtracting fractions are messy.

We're just adding and subtracting from both sides, in this case, subtracting.

Let's have some practice adding and subtracting negative numbers.

Welcome to the presentation on adding and subtracting fractions.

We were studying adding and subtracting decimals at the time.

Welcome to the presentation on adding and subtracting negative numbers.

I'm not adding or subtracting anything to that.

So subtracting fractions is very similar to adding fractions.

You could also attend the seminar on adding and subtracting negative numbers.

Subtracting 16 is the same thing as adding positive 16.

All we're doing is simplifying the sides, or adding and subtracting from them.

And then from that, adding a negative 0.79 is equivalent of subtracting 0.79.

And this is a little bit of review of adding and subtracting negative numbers.

We're just adding or subtracting the same quantities on both sides.

And you can see for yourself, this all fits our traditional notion of adding and subtracting.

Subtracting 20. And subtracting 3 ones.

You could also do your adding or subtracting below the line, like this.

So if you're subtracting a negative number it's like adding a positive number.

If you've seen the video on adding and subtracting negative numbers, you probably should watch first.

Now just to kind of finish up this kind of idea of adding and subtracting vectors.

So you can't merge, when you're adding and subtracting, the real part to the imaginary part.

We're subtracting 400, and we're subtracting 150.

Subtracting off the new cost, and adding that amount of money to the person that sold it.

So we're subtracting 40, and we're subtracting 2.

We're subtracting 42. We're subtracting 40 and 2.

But I think that right now that you might be ready to do the adding and subtracting module.

Once you go ahead and start, even the tiresome work of adding and subtracting figures is interesting in its way.

That won't change by adding or subtracting the same thing to both sides of the inequality.

So what's the set of all of the vectors that I can represent by adding and subtracting these vectors?

And we're subtracting this. We're subtracting 600 plus 50 plus 9.

I really encourage you to visualize the number line and really move along it depending on whether you're adding or subtracting.

Now, just like when you're adding fractions, when you're subtracting fractions, you have to have a common denominator.

When you're subtracting 8 you're subtracting another 6.

With that scare, I got busy changing my diet radically, adding and subtracting things most of you would find almost assuredly shocking.

And then the imaginary parts we have 2i so plus 2i and then we have a 7i or we're adding or we're subtracting 7i

So we're subtracting 3 from that side, and subtracting 3 from the right side.

And from that, we're subtracting 42.

We have both of these terms, they're both positive, we're adding we're not subtracting, they have different coefficients underneath here.

I'm subtracting 8x.

Or another way of thinking about it, we're subtracting 600, we're subtracting 50, we are subtracting 9.

And this number right here, we are subtracting 8 thousands we are subtracting 0 hundreds.

So you distribute the negative sign subtracting at three and then you're subtracting the two fifths.

And we're adding 4.

We're subtracting 2 x's.
