Question

calculati:2+{222:2•2+[92+2•4•(29–14•2:7)•9]•100}

Answer 1

2+{222:2•2+[92+2•4•(29–14•2:7)•9]•100}=
= 2+{111×2+[92+2×4×(29-28:7)×9]×100}=
=2+{222+[92+2×4×(29-4)×9]×100}=
=2+[222+(92+2×4×25×9)×100]=
=2+[222+(92+2×100×9)×100]=
=2+[222+(92+200×9)×100]=
=2+[222+(92+1800)×100]=
=2+(222+1892x100)=
=2+(222+189200)=
=2+189422=189424

Answer 2

=2+[111·2+(92+8·25·9)·100]=2+[222+(92+1500)·100]=2+(222+1592·100)=2+222+150000=
