It is expected that YOU can independently complete all of the previous numeric and algebraic examples without a calculator. If you are able to, GREAT!, as you will be able to really focus on Geometry this year!!! Seek immediate help if you are unable to perform these necessary ideas!
YOUR FIRST PRACTICE! BE ABLE TO COMPLETE PROBLEMS WITHOUT A CALCULATOR CHECK YOUR WORK WITH EACH OTHER, WITH A CALCULATOR, OR WITH THE ONLINE TOOLS! WELL DISCUSS THE PRACTICE AT THE END OF THIS LESSON…BE READY FOR THE CONCEPT QUIZ!!!
