Interpreting Numerical Expressions by Writing them in Sentences
By HoodaMathTutorials
The instructor dressed as a pig shows three numerical expressions and how he converts them to their mathematical sentence format. The problems are: (8 + 4) / 2; 8 * 4 + 2; and 8 * (4 + 2). He shows how the placement of parentheses and the order of operations change the way the problem is written. He does not actually solve them but this can be easily done with your students in class.

Multiply and divide rational expressions with polynomial numerators and denominators
By Khan Academy
Sal performs the following division and simplifies the result: (2p+6)/(p+5) ��������������������� (10)/(4p+20).
Multiply and divide rational expressions with monomial numerators and denominators
By Khan Academy
Sal performs the following division and simplifies the result: (2p+6)/(p+5) ��������������������� (10)/(4p+20).
Simplify numerical radical expressions with multiple terms
By Khan Academy
Sal shows how to manipulate expressions like 1/2 and 12/(2-5) so there's no radical in the denominator. This is called rationalizing the denominator.45
