Q.1

A)5+10-3*2/6 => 5+10-6/6=> 5+10-1=14

B) -25-5*3+8/2=> -25-15+8/2=> -25-15+4=-36

C) (3+7)*2+(15+3)*4=>10*2+18*4=> 20+72=92

D)68+32/(-8)=> 68+-4=64

E) 48+ ((-11+3)*2+4+24/7=> 48+(-8*2+28/7)=> 48+(-16+4)=> 48+-12=36

Q.2

A)114 000-26 000

26 000+40 000 => 140 000 140 000

1-48% 26 000+76923.077 => 102 923.077 = 1.360

B)-45-((-5)+5*21 => -40+105 => 65/-13= -5

-6+49/(-7) -6+-7

C) 150 000 => 150 000 = 600 000

1-3/4 .25

D) 80 000*(2-1.60) = 80 000*0.40 = 32 000 = 1.60

80 000*(2-1.60)- 12 000 80 000*0.40-12000 20 000

E) ((20 000*.50) + (10 000*.50))* 6.145- ((70 000*.70)+(80 000*.70))=

(10 000+5 000) * 6.145- (49 000+ 56000)

15 000*6.145-105 000

92 175- 105 000= - 12 825

Q.3

A)(-5)2 => -5*-5=25

B) (52)3 => 5(2*3) => 56 => 5*5*5*5*5*5= 15 625

C) 53*5-2=>(5*5*5)* (1/52) => 125 * (1/25) => 125*0.04= 5

D) 63/24=> (6*6*6)/(2*2*2*2) => 216/16 => 13.50

E)9-3/92 => (1/93)/(9*9)=> (1/729)/81= 0.0000169351

Q.4

A)163/4=> 4√163 => 4√(2*2*2*2)3 => 4√(24)3 => 4√24*3 => 4√212 => 212/4 => 23 = 8

B) 45/2 => -2√45 => -2√(2*2)5 => -2 √22*5 => -2√210 => 2 10/-2 => 2-5 = 0.03125
