Watch the video on “Order of operations” and answer:

• a)  What operations do we have to do before exponents?
• b)  What operations do we have to do after exponents?
• c)  Solve:
  • (7+1) + (9/3)
  • (3–1 ) / (1+1)
• d)  Solve:
  • 3² ∙ 7
  • (2⁴ +1) ∙ 3
  • 10 – (256/4³)
• e)  In what order do we have to do two operations if they are “tied for priority” (multiplication and division) or (addition and subtraction)?
• f)   Solve:
  • 40 / 5 ∙ 3
  • 2 ∙ 4 ∙ 3 / 8
  • 8 + 4 – 5 – 1
