[-12]+7

[-54]-[-76]

[-54]-24

[-56]+-22-[-51]+33

-22-[-77]-[-32]-[-15]

22+23+[-19]+18

180;[-15]*3

-3*-2

-7*9

Answer 1

(-32)+[-12] = -32-12 = -44

[-12]+7 = 7-12= -5

[-54]-[-76] = - 54+76 = 22

[-54]-24= -54-24= -78

[-56]+-22-[-51]+33= -56-22+51+33= 84-78 = 6

-22-[-77]-[-32]-[-15]= -22+77+32+15= 124-22 = 102

22+23+[-19]+18 = 46-19+18=64-19=45

180;[-15]*3= 180:(-45)= -4

-3*-2= 6

-7*9= -63

Answer 2

(-32)+[-12] = -32 - 12 = -44

[-12]+7 = -5

[-54]-[-76] = -54 + 76 =22

[-54]-24 = -79

[-56]+-22-[-51]+33 = -56 - 22 + 51 + 33 = 6

-22-[-77]-[-32]-[-15] = -22 + 77 + 32 + 15 = 102

22+23+[-19]+18 = 22 + 23 - 19 + 18 = 44

180;[-15]*3 = -15*3 = -45

-3*-2 = 6

-7*9 = -63
