Answer 1

Răspuns:

52+(64-25:5)×2=52+59×2=52+118=170

309-3×(100-72:9)=309-3×92=309-276=33

84-120:(90×2:10-6)=84-120:12=74

(99+3)×21×0:7=102×21×0=0:7=0

104:2+(6+36:6)×5=52+12=64

4+4×(4+4×4)-36:9:2=4-20-4÷2=4-20-2=14

(5+5×3)3-(3×25+24):3=20×3-99:3=60-33=27

(25+25)×3-(25+25×3):5=50×3-150:5=150-30=120

400-2×10+(650+310:3)=400-20+430=30-20=10

8+3 (12:4+21:7:3)=8+3=11+4=15

10+10:(10×10-10×9)=10+10+10=30

127+(36:9-1)8:2=127+3×4=127+12=139

Sper că team ajutat!!!!
