Steps to Evaluate Expressions

1. Replace each letter in the expression with the assigned value. 2. Perform the operations in the expression using the correct order of operations.

Example: 2x + 4 , when x = 3

Solve the following problems using the number given for the variable. Work out each problem on the left and answer column on the right.

SIMPLIFYINGALGEBRAIC

EXPRESSIONS

Combining Like Terms

In algebraic expressions, like terms are terms that contain the same variables,

such as 2n and 5n.

Variables are the letters that follow a coefficient, like x or y or even m or b.

Think of it this way: 2n and 5n are like brother and sister – they have the same last name, n.

Only the numerical coefficients are different.

Are these like terms?

5x and 5y

No, they are not, because they contain different variables.

What about these?5x and 6x?

Yes, because they contain the same variables.

Coefficients are the constants that come before a variable.

In our example 2n and 5n, the coefficients are 2 and 5.

Now that you know what these things mean, let’s try an example and combine like terms.

This expression has 2 terms. 2 and 5 are the coefficients, and the n’s are the variables.

2n + 5nmeans that you have 2 n’s and are adding

5 n’s to them.

So isn’t 2n + 5n the same as saying nn + nnnnn?

It is! How many n’s do you have?2n + 5n = 7n

Let’s do some more.

7p + 3p =

That means ppppppp + ppp

How many do you have all together?

You have 10 p’s, so7p + 3p = 10p

You try some.

4x + 12x =

5b + 14b =

15c – 9c =

10f – 2f =

How did you do?

4x + 12x = 16x

5b + 14b = 19b

15c – 9c = 6c

10f – 2f = 8f

Getting it? Great!

Now, what if you were asked to simplify an expression like this:

2a + 3a + 4a?

Everyone here has the same last names, so you can just combine them.

aa + aaa + aaaa = aaaaaaaaa

So, 2a + 3a + 4a = 9a

You doing great, so let’s try some more.

How in the world would you simplify an expression like this?

2a + 3a + 4d?

What’s up with that different last name?

It’s no big deal – watch. You can’t combine terms with different last names, so this is

what you do.

2a + 3a +4d

just means you have 2 a’s plus 3a’s plus 4d’s.

aa + aaa + dddd

SO,Combine like terms and you will get

5a + 4d.That’s it!!!!! That’s how you simplify that!

This is fun. Let’s do some more.

3a + 4a + 5x =

5a + 2a + 7g =

6b + 2a + 2b =

10x + 3y + 4x =

How did you do? Did you remember to just combine the like terms?

3a + 4a + 5x = 7a + 5x

5a + 2a + 7g = 7a + 7g

6b + 2a + 2b = 8b + 2a

10x + 3y + 4x = 14x + 3y

If you got them all, you’re sharp! Did you notice we mixed up the numbers? It

doesn’t matter in what order they appear – just put the same last name together!

If you are having trouble with this, we’re going to take a moment to get you on track.

If a’s are apples and p’s are peaches, and we tell you Jane brought in 3 apples, Mike

brought in 3 peaches and Susan brought in 3 apples, what would you have?

You’d have 3a + 3p + 3a, right?

If you combine your like terms, you would have

3 apples plus 3 peaches plus 3 apples.

3a + 3p + 3awhich would equalaaa + ppp + aaa

SO,aaa + ppp + aaa = 6a + 3p

Isn’t that easy? Better than writing all those a’s and p’s!

Okay, you combining like terms masters,let’s really rock. Try these. They are longer

and more involved, but you can do them.Just put the same last names together, but don’t try to combine different last names..

3v + 6p + 4p + 2v

4b + 7b + 9r + 2b + 2r

12c – 4c + 3d + 4d

3v + 6p + 4p + 2v = 5v + 8p

4b + 7b + 9r + 2b + 2r = 13b + 11r

12c – 4c + 3d + 4d = 8c + 7d

That last one was a little tricky, wasn’t it?Just remember that the sign ( + or - ) right in

front of a number belongs to that number.We want to show you something else.

What if we gave you this expression?

12c – 4c + 3d + 4d – 3d – 2c

Wow. We can do this. Let’s start with the c’s.

12c – 4c – 2c leaves you with 6c.

Now deal with the d’s. 3d + 4d – 3d leaves you with 4d. It’s not a

negative 4, it’s positive, so it’s +4d.

The solution is 6c + 4d. Remember that the sign in front of a number belongs to that

number.We want to show you one more.

What do you make of this?

5w + w = ?

That w all by itself is the same as 1w. We just don’t write the one, because in the

mathematical world, it is understood that it is just one. Don’t make the mistake of forgetting to include all the terms. If you

need to write the 1 in front of a variable to help you remember, go ahead. It’s okay

with us.

So 5w + w is the same as 5w + 1w which equals 6w.
