  (1) Let h be (-78)/(-24) + (-3)/12. Suppose h*z - 42 = -z + 2*f, z = f + 8. What is the remainder when 24 is divided by z?
  (2) What is 62991 to the power of 1/2, to the nearest integer?
  (3) Suppose 5 = -p, -4*z - 15 = 5*p + 6. Let l be 8 + 9/9*(-8 + 3). Solve -m = 2*j + z, -13 = l*j - 2*m + 6 for j.
  (4) Calculate prob of picking 1 j, 1 n, and 2 g when four letters picked without replacement from innvgninjnngvnn.
  (5) What is 82497.11cm in kilometers?
