Step-by-step explanation:
(vi) 12 ( 6 + 2 )
72 + 24
96
Add The following
(i) 7314 + 348 + 7314 + 121
7662 + 7435
15097
(ii)398 + ( - 2 ) + 1734 + ( - 1034 )
398 - 2 + 1734 - 1034
396 + 700
1096
(iii) 300 + ( - 78 ) + ( - 22 )
300 - 78 - 22
200
(iv) ( - 365 ) + ( - 35 ) + 1400
- 365 - 35 + 1400
1000
(v) 5 + 425 + ( - 275 ) + 600
430 - 275 + 600
755
Simplify the following :
(a) 132 - 143 + 96 - ( - 24 )
- 11 + 120
109
(b) 150 - ( - 148 ) + 2
150 + 148 + 2
300
(c) - 178 - 522 + ( - 410 )
- 700 - 410
- 1110
(d) 12 + ( - 36 ) - ( - 42 ) + 23
12 - 36 + 42 + 23
- 24 + 65
41
10. Let the other integer be x
x + ( - 246 ) = 418
x = 418 + 246
x = 664
11. Let the other integer be x
x + ( - 43 ) = - 72
x = - 72 + 43
x = - 23
