# Interactive video lesson plan for: Order of operations: more challenging examples (pre-algebra/grade 7 math)

#### Activity overview:

In this second part of a lesson on the order operations we will solve more challenging examples that have more operations than the ones in part 1. The expressions include exponents plus other operations. In these examples, divisions are written with a fraction line, which means that the division is done last. It is as if there were parentheses around the numerator and the denominator.

I also explain why we can do multiplications and divisions in any order IF the expression only contains multiplications & divisions, and no other operations. This boils down to the fact that each division can be written as a multiplication by the reciprocal of the divisor.

In my last example, we touch on decimal operations (decimal multiplication & division).

The first part of this lesson explains what the order of operations is, and can be found at https://www.youtube.com/watch?v=Hm1dvcVhnwA
