**1. Subtract the first integer from the second in each of the following:**

**(i) 12, -5**

**(ii) â€“ 12, 8**

**(iii) â€“ 225, – 135**

**(iv) 1001, 101**

**(v) â€“ 812, 3126**

**(vi) 7560, – 8**

**(vii) â€“ 3978, – 4109**

**(viii) 0, – 1005**

**Solution:**

(i) 12, -5

So by subtracting the first integer from the second

-5 â€“ 12 = – 17

(ii) â€“ 12, 8

So by subtracting the first integer from the second

8 â€“ (-12) = 8 + 12 = 20

(iii) â€“ 225, – 135

So by subtracting the first integer from the second

-135 â€“ (-225) = 225 â€“ 135 = 90

(iv) 1001, 101

So by subtracting the first integer from the second

101 â€“ 1001 = – 900

(v) â€“ 812, 3126

So by subtracting the first integer from the second

3126 â€“ (-812) = 3126 + 812 = 3938

(vi) 7560, – 8

So by subtracting the first integer from the second

-8 â€“ 7560 = – 7568

(vii) â€“ 3978, – 4109

So by subtracting the first integer from the second

-4109 â€“ (-3978) = – 4109 + 3978 = -131

(viii) 0, – 1005

So by subtracting the first integer from the second

-1005 â€“ 0 = – 1005

**2. Find the value of:**

**(i) â€“ 27 â€“ (- 23)**

**(ii) â€“ 17 â€“ 18 â€“ (-35)**

**(iii) â€“ 12 â€“ (-5) â€“ (-125) + 270**

**(iv) 373 + (-245) + (-373) + 145 + 3000**

**(v) 1 + (-475) + (-475) + (-475) + (-475) + 1900**

**(vi) (-1) + (-304) + 304 + 304 + (-304) + 1**

**Solution:**

(i) â€“ 27 â€“ (- 23)

So we get

= – 27 + 23

On further calculation

= 23 â€“ 27

We get

= – 4

(ii) â€“ 17 â€“ 18 â€“ (-35)

So we get

= – 35 + 35

On further calculation

= 0

(iii) â€“ 12 â€“ (-5) â€“ (-125) + 270

So we get

= – 12 + 5 + 125 + 270

On further calculation

= 400 â€“ 12

We get

= 388

(iv) 373 + (-245) + (-373) + 145 + 3000

So we get

= 373 â€“ 245 â€“ 373 + 145 + 3000

On further calculation

= 3145 + 373 â€“ 373 â€“ 245

We get

= 3145 â€“ 245

By subtraction

= 2900

(v) 1 + (-475) + (-475) + (-475) + (-475) + 1900

So we get

= 1 â€“ 950 â€“ 950 + 1900

On further calculation

= 1900 + 1 â€“ 1900

We get

= 1

(vi) (-1) + (-304) + 304 + 304 + (-304) + 1

So we get

= – 1 + 1 â€“ 304 + 304 â€“ 304 + 304

On further calculation

= 0

**3. Subtract the sum of â€“ 5020 and 2320 from â€“ 709.**

**Solution:**

We know that the sum of 5020 and 2320 is

-5020 + 2320

It can be written as

= 2320 â€“ 5020

So we get

= – 2700

Subtracting â€“ 709 we get

= – (-2700) + (-709)

On further calculation

= – 709 â€“ (-2700)

We get

= – 709 + 2700

By subtraction

= 1991

**4. Subtract the sum of â€“ 1250 and 1138 from the sum of 1136 and – 1272.**

**Solution:**

We know that the sum of â€“ 1250 and 1138 is

-1250 + 1138

It can be written as

= 1138 â€“ 1250

So we get

= – 112

We know that the sum of 1136 and â€“ 1272 is

1136 â€“ 1272 = – 136

So we get

-136 â€“ (-112) = – 136 + 112 = -24

**5. From the sum of 233 and â€“ 147, subtract â€“ 284.**

**Solution:**

We know that the sum of 233 and â€“ 147 is

233 â€“ 147 = 86

Subtracting â€“ 284 we get

86 â€“ (-284) = 86 + 284 = 370

**6. The sum of two integers is 238. If one of the integers is â€“ 122, determine the other.**

**Solution:**

It is given that

Sum of two integers = 238

One of the integers = – 122

So the other integer = – (-122) + 138

On further calculation

Other integer = 238 + 122 = 360

**7. The sum of two integers is â€“ 223. If one of the integers is 172, find the other.**

**Solution:**

It is given that

Sum of two integers = – 223

One of the integers = 172

So the other integer = – 223 â€“ 172 = – 395

**8. Evaluate the following:**

**(i) â€“ 8 â€“ 24 + 31 â€“ 26 â€“ 28 + 7 + 19 â€“ 18 â€“ 8 + 33**

**(ii) â€“ 26 â€“ 20 + 33 â€“ (-33) + 21 + 24 â€“ (-25) â€“ 26 â€“ 14 â€“ 34**

**Solution:**

(i) â€“ 8 â€“ 24 + 31 â€“ 26 â€“ 28 + 7 + 19 â€“ 18 â€“ 8 + 33

We get

= – 8 â€“ 24 â€“ 26 â€“ 28 â€“ 18 â€“ 8 + 31 + 7 + 19 + 33

On further calculation

= – 32 â€“ 26 â€“ 28 â€“ 26 + 38 + 19 + 33

It can be written as

= 38 â€“ 32 â€“ 26 â€“ 28 + 33 â€“ 26 + 19

So we get

= 6 â€“ 26 â€“ 28 + 7 + 19

By calculation

= 6 â€“ 28 â€“ 26 + 26

= 6 â€“ 28

By subtraction

= – 22

(ii) â€“ 26 â€“ 20 + 33 â€“ (-33) + 21 + 24 â€“ (-25) â€“ 26 â€“ 14 â€“ 34

We get

= – 46 + 33 + 33 + 21 + 24 + 25 â€“ 26 â€“ 14 â€“ 34

On further calculation

= – 46 + 66 + 21 + 24 + 25 + (-74)

It can be written as

= – 46 + 66 + 70 â€“ 74

So we get

= – 46 â€“ 4 + 66

By calculation

= – 50 + 66

= 66 â€“ 50

By subtraction

= 16

**9. Calculate **

**1 â€“ 2 + 3 â€“ 4 + 5 â€“ 6 + â€¦â€¦â€¦ + 15 â€“ 16**

We get

= – 1 â€“ 1 â€“ 1 â€“ 1 â€“ 1 â€“ 1 â€“ 1 â€“ 1

By calculation

= – 8

**10. Calculate the sum:**

**5 + (-5) + 5 + (-5) + â€¦..**

**(i) if the number of terms is 10.**

**(ii) if the number of terms is 11.**

**Solution:**

(i) if the number of terms is 10

We get

5 + (-5) + 5 + (-5) + 5 + (-5) + 5 + (-5) + 5 + (-5)

On further calculation

= 5 â€“ 5 + 5 â€“ 5 + 5 â€“ 5 + 5 â€“ 5 + 5 â€“ 5 = 0

(ii) if the number of terms is 11

We get

5 + (-5) + 5 + (-5) + 5 + (-5) + 5 + (-5) + 5 + (-5) + 5

On further calculation

= 5 â€“ 5 + 5 â€“ 5 + 5 â€“ 5 + 5 â€“ 5 + 5 â€“ 5 + 5 = 5

**11. Replace * by < or > in each of the following to make the statement true:**
