Explicație pas cu pas:
( 99-b -3x8 ) +2x3 = 16+50
(99-b -24 ) +6= 66
(99-b-24)=66-6
(99-b-24)=60
99-b=60+24
99-b=84
b= 99-84
b= 15

(6x4+c)- 24=4
24+c= 4+24
24+c= 28
c= 28-24
c= 4

(2x3+d) -( 7x9+6) = 49
(6+d) - (63+6)= 49
6+d= 49+69
6+d= 118
d= 118-6
d= 112

( e- 5x6 +10x5) -50+4x8= 42
(e- 30+50)-50+32=42
(e-30+50)-50=42-32
(e-30+50)-50= 10
(e-30+50)= 10+50
e-30+50= 60
e-30=60-50
e-30=10
e= 10+30
e= 40

(96-3x4-5x8)+f-9x7=13
(96-12-40)+f-63=13
44+f-63=13
44+f=13+63
44+f= 76
f= 76-44
f= 32

(23-6x3+g) +3x9 -8x3 -28=34
(23-18+g) +27-24-28=34
(23-18+g) +27-24=34+28
(23-18+g) +27-24=62
(23-18+g) +27= 62+24
(23-18+g) +27= 86
23-18+g=86-27
5+g= 59
g= 59-5
g= 54

(3x9+7xh -53) +5x2 -( 12-4x2) =36
(27+7h -53)+10-4=36
(27+7h-53)+10=36+4
(27+7h-53)+10=40
27+7h-53=40-10
27+7h-53=30
27+7h= 30+53
27+7h= 83
7h= 83-27
7h= 56
h= 56:7
h= 8

8x8-32-( 6xl -51) - (40-2x10 )= 9
64-32- (6l -51)- 20=9
64-32-(6l-51)= 9+20
32-(6l-51) =29
32-29= 6l-51
6l-51=3
6l= 51+3
6l=54
l= 54:6
l= 9
