a. 3.2 x 10^4 + 1.95 x 10^6 = (3.2 + 1.95) x 10^4 = 5.15 x 10^4
b. 8.03 x 10^-8 - 4.82 x 10^12 = -4.82 x 10^12 - 8.03 x 10^-8 = -4.82 x 10^12 - 0.0000000803 = -4.82 x 10^12
c. 2.56 x 10^-2 x 4.82 x 10^12 = (2.56 x 4.82) x (10^-2 x 10^12) = 12.3712 x 10^10 = 1.23712 x 10^11
d. (1.95 x 10^6) / (3.2 x 10^4) = (1.95 / 3.2) x (10^6 / 10^4) = 0.609375 x 10^2 = 6.09375 x 10^1 = 60.9375
e. 2.56 x 10^-2 + 32.8 = 0.0256 + 32.8 = 32.8256
f. 4.82 x 10^12 x 256.7 = 1.238994 x 10^15
