Question 1

=17-(8.2)+(3.4)

=17-16-12

=13

=14-3+(24/3) x 2

=14-3+(8.2)

=14-3+16

=27

=(4+8) /2 + (13-3) x5

= (12 /2) + (10x5)

=6+50

=56

d) = -72 + (14x-3)

=-72-42

= -114

e) =-21 + ((-9x3) - ((24-4)x2))

=-21 ((-27)-(40))

=-21+-67

= -88

Question 2

= 201 000 .

62 000 + 34 000

0.62

= 201 000

134 000

= 3

b) =-12+18+(11X4)

-5(45/9)

= 6+44

-10

= -5

c) =88 000

4

3

=66 000

d) = 64 000 (1,10)

64 000 (1,10) - 17 600

= 70 400

70400 - 17600

=70 400

52 800

= 4

3

e) = (37 800 + 18 000) x 5,435 - 88 000

= 55 800 x 5,435 - 88 000

= 303 273 - 88 000

=215 273

Question 3

a) = -34 = (-3x-3x-3x-3) = 81

b) = (43)2 = (4x4x4)2 = 64¸2 = (64x64) = 4096

c) = 75 x 7-4 = (7x7x7x7x7) x 1 / 74 = 16807 / 2401 = 7

d) =153 = 15x15x15 = 3375 = 125

34 3x3x3x3 81 3

e) =10-2 = 1 = 1 = 1 .
