Question

cine mă poate ajuta​

Answer 1

a ) 9+8-6 = 17-6 = 11

b) 87-39+25 = 48+25 = 73

c ) 189-79+126 = 110+126 = 236

d ) 7 x 4 x 8 = 28 x 8 = 224

e ) 28:4x9 = 7x9 = 63

f) 81:9x6 = 9 x 6 = 54

g) ( 126 + a ) - 326 = 629

126 + a = 629 - 326

126 + a = 303

a = 303-126

a = 177

h) ( 321 + 98 + 186 ) - a ( aici nu am vazut intrebarea corect )

i) 90 x 8 - ( 30 x 4 + 20 x 9 )

720 - 120 + 180

600 + 180 = 780

j ) 2 x 9 + 7 x 6 + 3 x 8

18 + 42 + 24 = 84
