Calculadora del orden de las operaciones (PEMDAS)

Calcular $$$\left(\left(\left(1 + 3\right)^{2} - 9\right) 2 + 1\right)^{2}$$$.

Sumar:

$$$\left(\left({\color{red}\left(1 + 3\right)}^{2} - 9\right) 2 + 1\right)^{2} = \left(\left({\color{red}\left(4\right)}^{2} - 9\right) 2 + 1\right)^{2}$$$

Elevar a la potencia:

$$$\left(\left({\color{red}\left(4^{2}\right)} - 9\right) 2 + 1\right)^{2} = \left(\left({\color{red}\left(16\right)} - 9\right) 2 + 1\right)^{2}$$$

Restar:

$$$\left({\color{red}\left(16 - 9\right)} 2 + 1\right)^{2} = \left({\color{red}\left(7\right)} 2 + 1\right)^{2}$$$

Multiplicar:

$$$\left({\color{red}\left(7 \cdot 2\right)} + 1\right)^{2} = \left({\color{red}\left(14\right)} + 1\right)^{2}$$$

Sumar:

$$${\color{red}\left(14 + 1\right)}^{2} = {\color{red}\left(15\right)}^{2}$$$

Elevar a la potencia:

$$${\color{red}\left(15^{2}\right)} = {\color{red}\left(225\right)}$$$

El valor de la expresión es $$$225$$$A.
