#### Question 1:

(1) 8 + 6
(2) 9 + ( –3)
(3) 5 + ( –6)
(4) –7 + 2
(5) –8 + 0
(6) –5 + ( –2)

(1) 8 + 6 = 14
(2) 9 + ( –3) = 9 – 3
= 6
(3) 5 + ( –6) = 5 – 6
= –1
(4) –7 + 2 = –5
(5) –8 + 0 = –8
(6) –5 + ( –2) = – 5 – 2
= –7

#### Question 2:

Complete the table given below.
 + 8 4 –3 –5 –2 –2 + 8 = +16 6 0 –4

 + 8 4 –3 –5 –2 –2 + 8 = +6 –2 + 4 = +2 –2 – 3 = –5 –2 – 5 = –7 6 6 + 8 = 14 6 + 4 = 10 6 – 3 = 3 6 – 5 = 1 0 0 + 8 = 8 0 + 4 = 4 0 – 3 = –3 0 – 5 = –5 –4 –4 + 8 = 4 –4 + 4 = 0 –4 – 3 = –7 –4 – 5 = –9

#### Question 1:

Write the opposite number of each of the numbers given below.
 Number 47 + 52 – 33 – 84 – 21 + 16 – 26 80 Opposite number

 Numbers 47 + 52 – 33 – 84 – 21 + 16 – 26 80 Opposite numbers – 47 – 52 + 33 + 84 + 21 –16 + 26 – 80

#### Question 1:

Write the proper sings > , < or = in the boxes below.
 (1) –4    x   5 (2) 8    x    –10 (3) +9    x   +9 (4) –6    x    0 (5) 7    x    4 (6) 3    x    0 (7) –7    x   7 (8) –12    x    5 (9) –2    x   –8 (10) –1    x   –2 (11) 6    x   –3 (12) –14    x    –14

 (1)-4 < 5 (2) 8 > –10 (3) +9  = +9 (4) –6 < 0 (5) 7 > 4 (6) 3 > 0 (7) –7 < 7 (8) –12 <  5 (9) –2 > –8 (10) –1 > –2 (11) 6 > –3 (12) –14 =​ –14

#### Question 1:

Subtract the numbers in the top row from the numbers in the first column and write the proper number in each empty box.
 – 6 9 –4 –5 0 +7 –8 –3 3 3 – 6 = –3 8 8 – (– 5) = 13 –3 –2

 – 6 9 –4 –5 0 +7 –8 –3 3 3 – 6 = –3 3 – 9 = –6 3 + 4 = 7 3 + 5 = 8 3 – 0 = 3 3 – 7 = –4 3 + 8 = 11 3 + 3 = 6 8 8 – 6 = 2 8 – 9 = –1 8 + 4 = 12 8 – (– 5) = 13 8 – 0 = 8 8 – 7 = 1 8 + 8 = 16 8 + 3 = 11 –3 –3 – 6 = –9 –3 – 9 = –12 –3 + 4 = 1 –3 + 5 = 2 –3 – 0 = –3 –3 – 7 = –10 –3 + 8 = 5 –3 + 3 = 0 –2 –2 – 6 = –8 –2 – 9 = –11 – 2 + 4 = 2 –2 + 5 = 3 –2 – 0 = –2 –2 – 7 = –9
