Remember this?

5+−6−−8=

1. -3
2. 7
3. 8
4. -8

-8 + - 10 =
(only type in the answer)

Think about order of operations!

8 : 4 x 2 =

1. 1
2. 2
3. 3
4. 4

How does this work?
3a + 4a = ?
(only type in the answer)

Working away the brackets

Example:

3 (a + 5) = 

This becomes?
5 (a + 8) =

1. 5a + 13
2. 5a + 58
3. 5a + 40
4. 13a

And this?
-7(a + 5) =
(only type in the answer, without spaces)

4a (5a - 3) =

1. 9a​2​​−12a
2. 20aa+12
3. 1a​2​​−7a
4. 20a​2​​−12a

Final question!
Simplify: 18a + - 19a
