Answer 1

Răspuns:

Explicație pas cu pas:

(5x10-9x5)x5+35::(2x0x9:7+9:9)= (50 - 45)x5 + 35: (0 + 1) = 5x5 + 35 : 1 =

= 25 + 35 = 60

__________

(3x9+0:10):9+9:(0:5+5x2:10)=

(27 + 0) : 9 + 9 : (0 + 10 : 10) = 27: 9 + 9 : (0 + 1) = 3 + 9 : 1 = 3 + 9 = 12

Answer 2

Răspuns:

b)(5x10-9x5)x5+35:(2x0x9:7+9:9)=

(50-45)·5 + 35:(0+1)=

5·5+35:1=25+35=60

c)(3x9+0:10):9+9:(0:5+5x2:10)=

(27+0):9+9:(0+10:10)=

27:9+9:(0+1)=

3+9:1=12
