Last-Class-Before-Break Edition...

Algebra I

Today we discussed
We continued our discussion about factoring, and the number of solutions (zeroes, roots) an equation has based upon its degree.  We moved into solving equations.

Remember:

IF  ab = 0, then either a=0 or b=0 or both must be equal to zero.

Pre-Algebra

Today we discussed
We worked on turning fractions into decimals (remember!  a fraction is just a division problem), and we reviewed multiplying fractions and mixed numbers.

Things to remember when multiplying fractions and mixed numbers:

• Turn mixed numbers into fractions first.
• Next, simply by dividing out the Greatest Common Factor (GCF)
• Multiply Numerators
• Multiply Denominators
• Simply, if necessary.
