Question

1.a-(-b)= a +b. If a = 6 and b = 11
2.12 17+(-3)]=[12]+[12-3) ]
3.26 (-48) + (-48) (-36)
4.625 * (+35) + 625* 65
5.-12 [ -6 +3]
6.8*125(45)​

Answer 1

Answer:

1. a-(-b)=a+b

6-(-11)

6+11

17

2.12*17+(-3)=[12]+[12-3]

204-3=12+9

201=21

3.26 (-48)+(-48)(-36)

(-48)[26-36]

-48*-10

480

4.625*35+625*65

625 (35+65)

625×100

625000

5. -12 [-6+3]

-12*-3

36

6.8*125 (45)

1000*45

45000
