2a ( b - c ) + 4 ( e + d )

2(2) ( - 3 - 4) + 4 (6 + ( - 5))

4( - 7) + 4(6 - 5) - 28 + 4(1) - 28 + 4 - 24

3(c - d) + 4(e - a)

3(4 - ( - 5)) + 4(6 - 2)

3(4 + 5) + 4(4)

3(9) + 16

27 + 16

43

b / a + d / e - 3 / 2 + ( - 5 / 6) - 3 / 2 - 5 / 6 - 14 / 6

b ^ - a + c ^ b

( - 3) ^ - 2 + (4) ^ - 3

1 / 9 - 64

(1 - 576 / 9) - 575 / 9.
