\(\frac12 -(\frac38+\frac12-1) \times4 \times 25\)

 

Parenthesees:

\(\frac12 -(\frac38+\frac{1\times4}{2\times4}-\frac{8}{8}) \times4 \times 25 \\~\\ \frac12 -(\frac38+\frac{4}{8}-\frac{8}{8}) \times4 \times 25 \\~\\ \frac12 -(\frac{3+4-8}{8}) \times4 \times 25 \\~\\ \frac12 -(\frac{-1}{8}) \times4 \times 25 \\~\\ \frac12 + \frac{1}{8} \times4 \times 25\)

 

Multiplication and Division:

\(\frac12 +\frac{1\times 4 \times 25}{8} \\~\\ \frac12 +\frac{100}{8} \\~\\ \frac12 +\frac{100}{8} \\~\\ \frac 12 + \frac{25}{2}\)

 

Addition:

\(\frac{25+1}{2} \\~\\ \frac{26}{2} \\~\\ 13\)
