Explanation:

Step1: Solve direction problem 1

Start facing north. A $\frac{1}{4}$ clockwise turn (right turn) points to East. Mark this as B.

Step2: Solve direction problem 2

Start facing north. A $\frac{3}{4}$ clockwise turn: $\frac{3}{4}$ of a full turn lands on West. Mark this as C.

Step3: Solve direction problem 3

Start facing east. A $\frac{1}{4}$ counterclockwise turn (left turn) points to North. Mark this as D.

Step4: Solve direction problem 4

Start facing west. A turn less than $\frac{1}{4}$ clockwise points between West and North (northwest area). Mark this as E.

Step5: Solve direction problem 5

Start facing north. A clockwise turn between $\frac{1}{2}$ (south) and $\frac{3}{4}$ (west) points between South and West (southwest area). Mark this as F.

Step6: Solve direction problem 6

Start facing north. A counterclockwise turn between $\frac{1}{4}$ (west) and $\frac{1}{2}$ (south) points between North and West (northwest area, further west than E). Mark this as G.

Step7: Calculate problem 7

Simplify $85*50 = 85*5*10$
$= 425*10 = 4250$

Step8: Calculate problem 8

Break down $416*6 = (400+16)*6$
$= 400*6 + 16*6 = 2400 + 96 = 2496$

Step9: Calculate problem 9

Compute $597*4 = (600-3)*4$
$= 600*4 - 3*4 = 2400 - 12 = 2388$

Step10: Calculate problem 10

Break down $1373*7 = (1000+300+70+3)*7$
$= 1000*7 + 300*7 + 70*7 + 3*7 = 7000 + 2100 + 490 + 21 = 9611$

Answer:

  1. B: East (marked on the circle at East)
  2. C: West (marked on the circle at West)
  3. D: North (marked on the circle at North)
  4. E: Between West and North (northwest region of the circle)
  5. F: Between South and West (southwest region of the circle)
  6. G: Between North and West (northwest region, further west than E)
  7. $4250$
  8. $2496$
  9. $2388$
  10. $9611$
