Question

calculati respectând regulile invatate a)52+(64-26:5)×2=
b)8+3×(12:4+27:7)=
c)27+36:4-1)×8×2=
​

Answer 1

$52 + (64 - 26 \div 5) \times 2 \\ 52 + (64 - 5.2) \times 2 \\ 52 + 58.8 \times 2 \\ 52 + 117.6 \\ 169.9$

$8 + 3 \times (12 \div 4 + 27 \div 7) \\ 8 + 3 \times (3 + 3.85) \\ 8 + 3 \times 6.85 \\ 8 + 20.55 \\ 28.55$

$(27 + 36 \div 4 - 1) \times 8 \times 2 \\ (27 + 9 - 1) \times 8 \times 2 \\ 37 \times 16 \\ 592$

Answer 2

52+(64-2,5)x2=
52+61,5x2=
52+123=175

8+3x(3+3,8)=
8+9+11,4=28,4

(27+36:4-1)x8x2=
(27+9-1)x8x2=
35x8x2=>280x2=560
