$-10-[11+(-10-6)+1]\\-10-[11-16+1]\\-10-4\\-16$

c)

$18-(14+15)-[13-(16-21)]\\18-29-[13+5]\\18-29-18\\-29$

d)

$-(-22)-[29+(27-23-26)-28]\\22-[29-22-28]\\22-21\\1$

e)

$9-(-10)-[-21-(-13-13+25)]-(-18)\\9+10-[-21+1]+18\\9+10+20+18\\57$

f)

$11+[-17-(-22+16)+(-29)]-(-46+54)\\11+[-17+6-29]-8\\11-40-8\\-37$
