Question

Calculează: a) 3+ (4 × 9) + [(15 x 6): 10 - 14:2]= ,
15-3+2×[7×(24:8-15:3= b)215+270:[48:6+(18×3+28)]
390: 3 + [16×(28:7)+(12×4: 16)] urgent va rog dau 35 de puncte​

Answer 1

3 + (4 x 9) + [(15 x 6): 10 - 14:2] = 3 + 36 + [90:10 - 7] = 3 + 36 + [9 - 7] = 3 + 36 + 2 = 41          

390: 3 + [16x(28:7)+(12x4: 16)] = 390 : 3 + [16x(4)+(12x4: 16)] = 390/3 + [16x(4)+(12x4/16)] = 130 + [16x(4)+(3)] = 130 + 64 + 3 = 197
