resuelve las siguientes operaciones combinadas​

Answer 1

Respuesta:

$1.$

$1)8 \times 3 - (6 - 3) + 7 = \\ 8 \times 3 - 3 + 7 = \\ 24 - 3 + 7 = \\ 21 + 7 = \\ 28$

$2)(12 + 8) \div 2 - (10 - 3) = \\ 20 \div 2 - 7 = \\ 10 - 7 = \\ 3$

$3)25 + 7 + 40 \div 5 - (10 - 5) = \\ 25 + 7 + 8 - 5 = \\ 32 + 8 - 5 = \\ 40 - 5 = \\ 35$

$4)(12 + 8 + 20 - 10) \times 3 \div (25 - 15) = \\ (20 + 20 - 10) \times 3 \div 10 = \\ (40 - 10) \times 3 \div 10 = \\ 30 \times 3 \div 10 \\ 90 \div 10 = \\ 9$

$5)(5 + 8 + 3) \div 4 \times (12 - 6) = \\ (13 + 3) \div 4 \times 6 = \\ 16 \div 4 \times 6 = \\ 4 \times 6 = \\ 24$

$6)(52 + 11) \div 9 + (15 \div 5) = \\ 63 \div 9 + 3 = \\ 7 + 3 = \\ 10$

$2.$

$6 \times 5 - (7 + 8) + 2 = \\ 6 \times 5 - 15 + 2 = \\ 30 - 15 + 2 = \\ 15 + 2 = \\ 17$

$6 \times 7 \div (6 - 4) - 6 = \\ 6 \times 7 \div 2 - 6 = \\ 42 \div 2 - 6 = \\ 21 - 6 = \\ 15$

$(7 \times 5) - (17 + 11) \div 2 = \\ 35 - 28 \div 2 = \\ 35 - 14 = \\ 21$

$(12 + 12 - 4) \div [(15 - 7) \div 4] = \\ (12 + 12 - 4) \div (8 \div 4) = \\ (24 - 4) \div 2 = \\ 20 \div 2 = \\ 1 0$

$(21 \times 2) \div (20 - 14) = \\ 42 \div 6 = \\ 7$
