### Anabelle's Blog Post: Equivelant Expressions

Combining Integers
Positive + positive= always positive | ex. 3 + 5= 8
Negative + Negative= always negative | ex. -4 -6= -10
Negative + Positive= will always keep the sign of the greatest absolute value | ex. -5 + 7= 12
Positive + Negative= same as negative + positive | 5 - 7= -2
________

Multiplying Integers
Positive x Positive= Positive | ex. (5)(2)=10
Negative x Negative= Positive | ex. (-2)(-3)= 6
Negative x Positive= Negative | ex. (3)(-5)= 15
Positive x Negative= Negative | ex. (-2)(4)= 8

________
Combining Like Terms

Step 1: Collect terms in order of alphabet and degree (in that order) from left to right.

Step 2: Combine and Simplify

When we combine the terms we show our work on the side like this:

________

Removing Brackets while collecting like terms
Step 1: Look at the signs in front of each bracket. If positive simply remove the bracket and keep the terms the same. (Drop the + sign.)

Step 2: Collect like terms.

Step 3: Simplify.

Here is another example:

_______

Step 1: If it is negative multiply out each term by negative and rewrite. (Like switching signs.)

Step 2: Combine like terms.

Step 3: Simplify.

Here is another example:

________
