Activity Five: BIMDAS and Negative Numbers


When evaluating expressions with negative numbers that involve more than one mathematical operation you should follow the usual BIMDAS convention, as well as keeping in mind the rules for negative numbers

For example, consider the following:

a. 10 - (4 – 5)  
b. 10 – (4 + 5)  
c. 10(4 – 5)  
d. -10(4 – 5)
