Help solving 2&3 (2.3)

Suppose you deposit $806 ten from today and each year thereafter deposit $806 for a total of eight consecutive cash flows (CF's) i.e. eight consecutive annual CF's beginning ten years (t = 10) from today Calculate the present value today (t =0) of these CF's if the rate of interest is 5 4 percent compounded annually. Calculate the present value today (t = 0) of deposits in the amount of $212 made at the end of each month for ten consecutive years with the first of these deposits beginning at the end of five years plus one month (i.e 61 months) from today The rate of interest is 0.5 percent compounded monthly
