Order of Operations Evaluating Algebraic Expressions

I start by reviewing the Order of Operations (PEMDAS) and then work through 3 Arithmetic examples at 7:44 9:06 10:33 , 4 examples of Evaluating Algebraic Expressions 15:56 19:22 20:43 22:20 , 2 Application Examples 24:38 28:10 , and 1 Error Analysis example 32:57. Another error in the last example is I spelled equivalent as equivalent(which is incorrect).
