Question

1+3•{16+5•[243-(×-3•32)]} +1=2000​

Answer 1

1+3•{16+5•[243-(×-3•32)]} +1=2000

1+3•{16+5•[243-(×-96)]} +1=2000

1+3•{16+5•[243-(×-96)]} =2000-1

1+3•{16+5•[243-(×-96)]} =1999

3•{16+5•[243-(×-96)]} =1999-1

3•{16+5•[243-(×-96)]} =1998

16+5•[243-(×-96)] =1998:3

16+5•[243-(×-96)]=666

5•[243-(×-96)] =666-16

5•[243-(×-96)] =650

243-(×-96) =650:5

243-(×-96) =130

×-96 =130+243

×-96=373

×=373+96

×=469
