a)–5– 3.(– 2)
b)|– 11|
c)| 7 - 4| + |4 – 7|
d) 2 + 5.(-3) - (-4)
e) –11 - 2.(-3) + 3
f) –8 + 3. [2 – (-1)]
g) |2 + 3. (-2)| – |3+ 2.(-3)|
h) |5 – 10 |– |10 - (-5)| - | -5 -(-5)|

​

Answer 1

a)–5– 3.(– 2)

-8.-2= 16

b)|– 11| = 11

c)| 7 - 4| + |4 – 7|

|3| + |-3|

3+3= 6

d) 2 + 5.(-3) - (-4)

2 + (-15) + 4

-13 + 4 = - 9

e) –11 - 2.(-3) + 3

-11 + 6 + 3

-5 + 3 = - 2

f) –8 + 3. [2 – (-1)]

-8 + 3.3

-8+9= 1

g) |2 + 3. (-2)| – |3+ 2.(-3)|

|2 + (-6)| – |3+ (-6)|

|-4| – |-3|

4 - 3 = 1

h) |5 – 10 |– |10 - (-5)| - | -5 -(-5)|

|-5 |– |15| - | 0|

5 - 15 = - 10
