= -4

**Now, on the number line :**

**Question no – (2)**

**Solution :**

**(i) Given, -557 and 488**

∴ |-557|- |488|

= 557 – 488

= 69

Thus, the sum is 69.

**(ii) Given, -522 and -160**

= – 522 – 160

= – 682

Therefore, the sum is -682

**(iii) Given, 2567 and -325**

= 2567 – 325

= 2242

Therefore, the sum is 2242.

**(iv) Given, -10025 and 139**

= – 10025 + 139

= – 9886

Hence, the sum is -9886

= 6

**∴** It is False

**(iii) Given, |4 – 2| = |4| – |2|**

**∴** L.H.S = |4 – 2|

= 2

**∴** R.H.S = |4| – |2|

= 4 – 2

= 2

∴ It is True.

**(iv) Given, |(2) + (- 4) | = |- 2| + |4|**

**∴** L.H.S

|(- 2) + (- 4)|

= |2 + 4|

= 6

= -136 + 112

= -24

**Question no – (5)**

**Solution :**

1st the sum

= (233 – 147)

= 86

Now, the subtract,

= 86 – (-284)

= 86 + 284

= 370

**Question no – (6)**

**Solution :**

In the given question,

Sum of two integers = 238

One of the integers = 122

Other integer = ?

**∴** Other integers,

= – (-122) + 238 ‘

= + 122 + 238

= 360

Therefore, the other integer will be 360.

**Question no – (7)**

**Solution :**

In the given question,

Sum of two integers is = -223

One integers = 172

Other integers = ?

**∴** Other integer,
