Question

2012 + 201 – 201 x 3 + 201 : 3 + 2 x\(\frac{1}{4}\) x\(\frac{1}{2}\) x 4

Answer 1

\(2012+201-201\times3+201:3+2\times\frac{1}{4}\times\frac{1}{2}\times4\)

\(=2012+201\times\left(1-3+\frac{1}{3}\right)+2\times\frac{1}{2}\times4\times\frac{1}{4}\)

\(=2012+201\times\left(\frac{-5}{3}\right)+1\)

\(=2012-335+1\)

\(=1677+1\)

\(=1678\)
