Homework time.
+ Refresh Ch8 p.46/47, ONLY MAKE    R7 !
+ Do it COMPLETE WITH CALCULATIONS !
 
R7  Next slide shows you HOW.


Slide 15 - Slide

As you will understand, R7 asks complete Calculations from you, on paper.
Just answers are not enough. It's about the steps you have to take - in the right order! 
For example:
4 + 6 x 3 -4 =  4 + 18 - 4 = 22 - 4 = 18           and NOT:
4 + 6 x 3 - 4 = 4 + 18 = 22 = 22 -4  = 18,          because       22 is not equal to 18...
