TarEa 1

Resolver los siguientes ejercicios escribiendo el procedimiento y reducieendo a su máxima expresión.
1. (2)(3)(-5)(-2)(3)(-7)(8)=10080
2. (5)(-5)(3)+2+4-7-12+45-33+75=-1
3. -134-12+13+54-65+67(2)(-3)(4)=101
4. 12-44+36-76+89-55+243-74=141
5. (2)(3)(-4)(5)(-6)(7)(-8)(9)(0)=0
6. (12/5)(6/3) +(4/9)(8/11)=2536/495
7. 14/3 + 15/2 - 6/4 =-1107/26
8. (((12/5)(15/4)/(13/7)(16/9))(-5)) + 1/2 =-13771/6622
9. (13/22)/(43/15) - 16/7 =137/50
10. ((9/8)(8/6)/(25/4)) + ((13/45)(45/2)) - 16/4 =670155/321300
11. (33/17)(45/12) + 3/5 - 18/7 + 16/9 - 25/5 =2.08760971
