1) Уменьшаемое 91, вычитаемое — сумма чисел 26 и 38.
\(91 - (26 + 38) = \textcolor{#e03131}{\mathbf{27}}\)
\({1)\ 26 + 38 = \textcolor{#e03131}{\mathbf{64}}}\) \(\quad {2)\ 91 - 64 = \textcolor{#e03131}{\mathbf{27}}}\)
2) Первое слагаемое 37, второе слагаемое — разность чисел 65 и 29.
\(37 + (65 - 29) = \textcolor{#e03131}{\mathbf{73}}\)
