Today we had a Pre-Test, these are some the concepts that was included in the Pre-Test.

**Rational Numbers**

*Can be written as a fraction

*Fractions

*Whole Numbers

*Whole Numbers

*Mixed Numbers

*Decimals that end.

*Decimals With a Pattern.

**Irrational Number**

*Cannot be written as a Fraction

*Decimals with no end/repeating/pattern.

Radical Operations:

Adding/Subtracting:

When you have the same radicand/ike terms, you just simply add them together.

For Example:

---------------------------------------------------------------------------------------

When both radicands does not have the same value you might consider factoring the number so it can have the same value.

For Example:

------------------------------------------------------------------------------------------

*When a problem has same radicand but does not have the same root, you cannot add them together because they are not like terms.

For Example:

______________________________________________________________

**Multiplying:**

Dont forget to use FOIL whe multiplying.

---------------------------------------------------------------------------------------

Be careful when subtracting after multiplying! Only add the like terms.

Also don't forget that there's always a one before the root.

Rationalizing

The denominator is a sum of 3+

------------------------------------------------------------------------------------

The denominator is a difference of

The test is on Monday, so be ready for it.

Rationalizing

The denominator is a sum of 3+

**√**y, so we multiply numerator and denominator by the difference 3 -**√**y.------------------------------------------------------------------------------------

The denominator is a difference of

**√7 -****√5**, so we multiply numerator and denominator by the sum**√7 -****√5**The test is on Monday, so be ready for it.
