\(9 + 5 = \textcolor{#e03131}{\mathbf{14}}\)
\(8 + 5 = \textcolor{#e03131}{\mathbf{13}}\)
\(7 + 4 = \textcolor{#e03131}{\mathbf{11}}\)
\[\begin{aligned} 7 + 3 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{2}}\kern0.035em} &= 12 & \qquad 6 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{4}}\kern0.035em} + 7 &= 17 \\ 8 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{2}}\kern0.035em} + 6 &= 16 & \qquad 8 + 2 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{4}}\kern0.035em} &= 14 \\ 9 + 1 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{7}}\kern0.035em} &= 17 & \qquad 8 + 2 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{5}}\kern0.035em} &= 15 \\ 7 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em} + 5 &= 15 & \qquad 7 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em} + 3 &= 13 \\ 9 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{1}}\kern0.035em} + 2 &= 12 & \qquad 6 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{4}}\kern0.035em} + 5 &= 15 \end{aligned}\]
