1) $\mathbf{(2 + 3)^2 = 25}$

Primeiro o parêntese: $\mathbf{\textcolor{#3b82f6}{2 + 3} = \textcolor{#3b82f6}{5}}$ ; depois $\mathbf{\textcolor{#3b82f6}{5}^2 = \textcolor{#ef4444}{25}}$ .

2) $\mathbf{\sqrt{16} + 5 = 9}$

A raiz está no primeiro nível: $\mathbf{\sqrt{\textcolor{#3b82f6}{16}} = \textcolor{#3b82f6}{4}}$ ; depois $\mathbf{\textcolor{#3b82f6}{4} + 5 = \textcolor{#ef4444}{9}}$ .

3) $\mathbf{2 \times (1 + 2)^2 = 18}$

Primeiro o parêntese: $\mathbf{\textcolor{#3b82f6}{1 + 2} = \textcolor{#3b82f6}{3}}$ ; depois a potência: $\mathbf{\textcolor{#3b82f6}{3}^2 = \textcolor{#3b82f6}{9}}$ ; e por fim $\mathbf{2 \times \textcolor{#3b82f6}{9} = \textcolor{#ef4444}{18}}$ .

4) $\mathbf{\sqrt{25} + 3^2 = 14}$

A raiz e a potência estão no primeiro nível: $\mathbf{\sqrt{\textcolor{#3b82f6}{25}} = \textcolor{#3b82f6}{5}}$ e $\mathbf{\textcolor{#10b981}{3}^2 = \textcolor{#10b981}{9}}$ ; depois $\mathbf{\textcolor{#3b82f6}{5} + \textcolor{#10b981}{9} = \textcolor{#ef4444}{14}}$ .

5) $\mathbf{(10 - 2 \times 3)^2 = 16}$

Dentro do parêntese, a multiplicação vem antes da subtração: $\mathbf{\textcolor{#3b82f6}{2 \times 3} = \textcolor{#3b82f6}{6}}$ , e $\mathbf{\textcolor{#3b82f6}{10 - 6} = \textcolor{#3b82f6}{4}}$ ; depois $\mathbf{\textcolor{#3b82f6}{4}^2 = \textcolor{#ef4444}{16}}$ .

6) $\mathbf{[\sqrt{36} + 2] \times 3 = 24}$

Dentro do colchete, a raiz primeiro: $\mathbf{\sqrt{\textcolor{#3b82f6}{36}} = \textcolor{#3b82f6}{6}}$ , e $\mathbf{\textcolor{#3b82f6}{6 + 2} = \textcolor{#3b82f6}{8}}$ ; depois $\mathbf{\textcolor{#3b82f6}{8} \times 3 = \textcolor{#ef4444}{24}}$ .
