tarea 1

Resolver los siguientes ejercicios escribiendo el procedimiento y reducieendo a su máxima expresión.

1. (2)(3)(-5)(-2)(3)(-7)(8)= -10080
6
-30
60
180
-1260


2. (5)(-5)(3)+2+4-7-12+45-33+75= -1
-25 . 3=-75+6
-69-7=-76-12
-88+45=-43-33=-76
-76+75=-1


3. -134-12+13+54-65+67(2)(-3)(4)= 1848
-146+13=-133+54=-79
-79-65=144+67=-77
-77(2)=-154(-3)=462(4)=1848


4. 12-44+36-76+89-55+243-74= 131
-32+36=4-76=-72
-72+89=17-55=-38
-38+243=205-74=131


5. (2)(3)(-4)(5)(-6)(7)(-8)(9)(0)= 0
6(-4)=-24(5)=-120
-120(-6)=720(7)=5040(-8)=-40320
-40320(9)=-362880(0)=0


6. (12/5)(6/3) +(4/9)(8/11)= 5.12
(12/5)(2/1)+(4/9)(8/11)=
24/5+32/99= 5.12


7. 14/3 + 15/2 - 6/4 = 31/3
14/3+15/2=73/6
73/6-6/4=31/3


8. (((12/5)(15/4)/(13/7)(16/9))(-5)) + 1/2 = 14695/1040
((45/5)/(208/63)=2835/1040
(2835/1040)(-5/1)= 14695/1040


9. (13/22)/(43/15) - 16/7 = -3767/3360
559/480-16/7=-3767/3360


10. ((9/8)(8/6)/(25/4)) + ((13/45)(45/2)) - 16/4 =
(72/48)/(25/4)=(72/48)/(25/4)=18/75
18/75 + 585/90=45495/6750-16/4= 90990/3375


11. (33/17)(45/12) + 3/5 - 18/7 + 16/9 - 25/5 =
56280-18450=37830/7175+16/9=340470
340470+114800/64575=455270/64575-25/5=
