Answer 1

Explicație pas cu pas:

120+3×{56:8+3×[7×9+3×(500:2-200:5-99×2)]}-104:4=

120+3×{7+3×[63+3×(250-40-198)]}-26=

120+3×{7+3×[63+3×(210-198)]}-26=

120+3×[7+3×(63+3×12)]-26=

120+3×[7+3×(63+36)]-26=

120+3×(7+3×99)-26=

120+3×(7+297)-26=

120+3×304-26=

120+912-26=

120+ 886 =1006

Answer 2

120+3x{56:8+3x[7x9+3x(500:2-200:5-99x2)]}-104:4=

=120+3x{7+3x[63+3x(250-40-198)]}-26=

=120+3x[7+3x(63+3x12)]-26=

=120+3x[7+3x(63+36)]-26=

=120+3x(7+3x99)-26=

=120+3x(7+297)-26=

=120+3x304-26=

=120+912-26=

=1032-26=

=1006
