a: =-4*7*125*3=-500*21=-10500
b: =-24(21*2-142)
=-24*(-100)=2400
c: \(=-65\cdot87+65\cdot17-87\cdot17+87\cdot65=17\cdot\left(-22\right)=-374\)
d: \(=11\left(-31-43-26\right)=-11\cdot100=-1100\)
e: \(=\left(-168\right)\left(1+72+27\right)=-16800\)
j: \(=53\left(25-89-36\right)=53\cdot\left(-100\right)=-5300\)
