Course review
Review each learning objective in this topic, then open its concept explanation or question set.
Learning objective
• Use numbers in the form a x 10^k where 1 <= a < 10 and k is an integer. • Calculator/computer notation such as 5.2E30 is not acceptable.

Learning objective
• Use technology for amortization and annuity problems. • Payments are made at the end of each period in examinations. • Knowing the annuity formula may help, but it is not examined.
