Answer 15

\(7 + 5^2 \times (7 – 3)\)

Parentheses first:

\(7 + 5^2 \times \color{red}{(7 – 3)}\)

\(7 + 5^2 \times \color{red}{4}\)

Exponent next:

\(= 7 + \color{green}{5^2} \times 4 \)

\(=7 + \color{green}{25} \times 4\)

Multiplication next:

\(=7 + \color{blue}{25 \times 4}\)

\(=7 + \color{blue}{100} \)

Finally addition:

\(=7 + 100 \)

\(= 107\)
