1) Из числа 52 вычесть сумму чисел 27 и 15.
\(52 - (27 + 15) = \textcolor{#e03131}{\mathbf{10}}\)
2) К разности чисел 64 и 6 прибавить 9.
\((64 - 6) + 9 = \textcolor{#e03131}{\mathbf{67}}\)
3) К 8 прибавить разность чисел 71 и 7.
\(8 + (71 - 7) = \textcolor{#e03131}{\mathbf{72}}\)
4) Из суммы чисел 37 и 8 вычесть 6.
\((37 + 8) - 6 = \textcolor{#e03131}{\mathbf{39}}\)
