14.
$36 \times 3 + 27 \times 9 = 108 + 243 \\ = 351$
$59 \times 8 - 18 \times 5 = \\ = 472 - 90 \\ = 382$
$97 \times 3 - 47 \times 5 = \\ = 291 - 235 \\ = 35$
$5 \times (39 + 27) - (67 - 49) \times 3 = \\ = 5 \times 63 - 18 \times 3 \\ = 315 - 54 \\ = 261$
$6 \times (29 + 54) - 2 \times (52 - 27) = \\ = 6 \times 83 - 2 \times 25 \\ = 498 - 50 \\ = 448$
$27 \times (41 - 38) + 47 \times (92 - 83) \\ = 27 \times 3 + 47 \times 9 \\ = 81 + 423 \\ = 504$
