Answer 1

$40\cdot3+3+[45:5\cdot16-(25:5:5+16:2)]-15\cdot2=\\=120+3+[9\cdot16-(5:5+8)]-30=123+(144-9)-30=\\=123+135-30=258-30=228$

Answer 2

40*3+3+[45:5*16-(25:5:5+16:2)]-15*2=
=40*3+3+[45:5*16-(5:5+16:2)]-15*2=
=40*3+3+[45:5*16-(1+16:2)]-15*2=
=40*3+3+[45:5*16-(1+8)]-15*2=
=40*3+3+(45:5*16-9)-15*2=
=40*3+3+(9*16-9)-15*2=
=40*3+3+(144-9)-15*2=
=40*3+3+135-15*2=
=120+3+135-15*2=
=120+3+135-30=
=123+135-30=
=258-30=
=228
