꧁Hello, how are you?꧂

• Bom... vamos lá, baby!

A-

${\purple{61 - 4 \times ( - 15) + 202 \div ( - 2)}} \\ {\purple{61 + 60 + 202 \div ( - 2)}} \\ {\purple{61 + 60 - 101}} \\ {\purple{121 - 101}} \\ {\purple{20}}$

• Multiplique... 4 × 15 = 60.
• Divida... - ( 202 ÷ 2 ) = 101.
• Some... 61 + 60 = 121.
• Subtraia... 121 - 101 = 20.

B-

${\purple{47 + ( - 7) \times (77) - 27 + ( + 9) - ( - 1)}} \\ {\purple{47 - 539 - 27 + 9 - ( - 1)}} \\ {\purple{47 - 539 - 27 + 9 + 1}} \\ {\purple{57 - 539 - 27}} \\ {\purple{57 - 566}} \\ {\purple{ - 509}}$

• Multiplique...
