[tex]a)7 \times 8 + 27 = 56 + 27 = 83 \\ 6 \times 7 + 38 = 42 + 38 = 80 \\ 8 \times 9 - 45 = 72 - 45 = 27[/tex]
[tex]b)49 + 3 \times 9 = 49 + 27 = 76 \\ 27 + 9 \times 6 = 27 + 54 = 81 \\ 91 - 8 \times 6 = 91 - 48 = 43[/tex]
[tex]3 \times 2 \times 8 + 38 = 6 \times 8 + 38 = 48 + 38 = 86 \\ 3 \times 3 \times 7 - 47 = 9 \times 7 - 47 = 63 - 47 = 16 \\ 8 \times 7 \times 0 + 96 = 56 \times 0 + 96 = 0 + 96 = 96[/tex]
