MPM1D Order of Operations examples 2017-09-18

We spent most of the class working on evaluating expressions. We saw a few new things:

  • an exponent that was an expression instead of just a number
  • brackets inside brackets (nested brackets, we often say)
  • lotsa negative signs

I handed out two more lengthy pages from The first page only included integers, and the second page included fractions. You should be spending at least 15 minutes outside of class time practising with these questions.

If you’re finding this challenging, you should be spending more than 15 minutes. These are fundamental skills that will serve you well throughout high school – it’s worth taking the time now, I promise!
