Answer 1

Răspuns:

1. ((-3)×(-4)+(-5)-(-10))÷(-17)= -1

2. 16×(−3)+(−60)÷12−(−55)= 2

3. 156÷13×(−12)+(−12)×(−12)+15×(−1)= -15

4. (56−964)×(−6)÷8−(−13)×(−24)= 369

5. (-2)¹+(-2)²+(-2)³+...+(-2)⁵⁰=(-2)⁵¹-(-2)¹

6. -1+2-3+4-...-81+82=41

7. 1+(-2)×(-3)-(-4)×5-6+7-8×(-9)=100

8. (-1)²²²+(-1)⁵⁶⁷+(-1)¹⁴³= -1

9. 1+2-3-4+5+6-7-8+...-160= -160

10. 4²⁰⁰¹-3×4²⁰⁰⁰-3×4¹⁹⁹⁹-...-3×4¹⁰⁰¹=4¹⁰⁰¹
