    Efetuando a divisão (+42) : (-6) obtemos:

    • +7

    • -7

    • +6

    • -6

    • N.d.a.

    Correct Answer
    A. -7
    Explanation
    When dividing a positive number (+42) by a negative number (-6), the result will be a negative number. In this case, the division of 42 by 6 is 7, and since the divisor is negative, the quotient will also be negative. Therefore, the correct answer is -7.

    Um submarino está a 150m de profundidade. Ele sobe 100m depois mais 33 metros e depois desce 16 metros. Como podemos indicar a sua posição em relação ao nível do mar?

    • -17m

    • -13m

    • -33m

    • -21m

    • N.d.a

    Correct Answer
    A. -33m
    Explanation
    The submarine starts at a depth of 150m and then rises 100m, bringing it to a depth of 50m. It then rises an additional 33m, bringing it to a depth of 17m. Finally, it descends 16m, bringing it to a depth of -33m. This negative value indicates that the submarine is now 33m above sea level.

    • 11ºC

    • -11ºC

    • -10ºC

    Correct Answer
    A. -11ºC
    Explanation
    The initial temperature is -7ºC and it decreases by 4ºC. To find the final temperature, we subtract 4 from -7, resulting in -11ºC.

    Qual será o resultado das seguintes multiplicações:(-5) . (-5) e (10) . (-2) (Lembre-se: Na MULTIPLICAÇÃO dois sinais iguais resulta (+) e dois sinais opostos resulta (-)

    • 25 e 20

    • -25 e -20

    • 25 e -20

    • -25 e 20

    • N.d.a.

    Correct Answer
    A. 25 e -20
    Explanation
    The given question asks for the result of two multiplications. In the first multiplication, (-5) multiplied by (-5), two negative signs are being multiplied, which results in a positive sign. Therefore, the result is 25. In the second multiplication, (10) multiplied by (-2), there are two signs that are opposite to each other, which results in a negative sign. Therefore, the result is -20.

    Resolvendo a expressão (-8) + (-5) - (-12 + 8) + (-10)

    • -19

    • 19

    • -13

    • -15

    • 21

    Correct Answer
    A. -19
    Explanation
    The expression can be simplified by following the order of operations (PEMDAS/BODMAS). First, we solve the parentheses: (-12 + 8) equals -4. Then, we add the negative signs before each number: (-8) + (-5) - (-4) + (-10). Combining like terms, we have -8 - 5 + 4 - 10, which equals -19.

    Resolva: -12 + 10 + 8 - 20 - 16 + 5

    • -25

    • 25

    • 20

    • -30

    • -26

    Correct Answer
    A. -25
    Explanation
    To solve the given expression, we can combine the positive and negative numbers together. Starting with the negative numbers, we have -12, -20, and -16. When we add them together, we get -48. Now, let's add the positive numbers: 10, 8, and 5. Adding them gives us 23. Finally, we can subtract 48 from 23, which gives us -25. Therefore, the correct answer is -25.

    Um clube tem saldo de gols igual a -7. Durante um campeonato ele perde uma partida por 1x0 e ganha outra por 4x1. Qual será o seu saldo de gols?

    • -8

    • -7

    • -5

    • -3

    • 5

    Correct Answer
    A. -5
    Explanation
    The club initially has a goal difference of -7. In the first match, they lose by a score of 1-0, which further decreases their goal difference to -8. However, in the second match, they win by a score of 4-1, which increases their goal difference by 5. Therefore, the final goal difference is -8 + 5 = -3.
