Question

calculate:

1+2+3+4x[5+6x(7-16:8)-9]x10-142:2



vreau din aproape in aproape calcul nu direct
coronita!!

Answer 1

1+2+3+4×[5+6×(7-16:8)-9]×10-142:2=
=1+2+3+4×[5+6×(7-2)-9]×10-142:2=
=1+2+3+4×(5+6×5-9)×10-142:2=
=1+2+3+4×(5+30-9)×10-142:2=
=1+2+3+4×(35-9)×10-142:2=
=1+2+3+4×26×10-142:2=
=1+2+3+104×10-71=
=3+3+1040-71=
=6+1040-71=
=1046-71=
=975

Answer 2

1+2+3+4·[5+6·(7-16:8)-9]·10-142:2=
=3+3+4·[5+6·(7-2)-9]·10-71
=6+4·(5+6·5-9)·10-71
=6+4·(5+30-9)·10-71
=6+4·(35-9)·10-71
=6+4·26·10-71
=6+104·10-71
=6+1040-71
=1046-71
=975
