(−14)(−11) =
Responses
A 144144
B −144−144
C −154−154
D 154
The answer is D) 154.
To multiply two negative numbers, you simply multiply them as you normally would and the result will be positive.
So (−14)(−11) = 154.
A company's financial statement shows a loss of 228 million dollars for the last six months. Express the average loss for each month as an integer.
Responses
A −38 million dollars−38 million dollars
B 37 million dollars37 million dollars
C −33 million dollars−33 million dollars
D 42 million dollars
To find the average loss for each month, you need to divide the total loss by the number of months. As there are 6 months in the statement, you will divide the loss by 6.
Therefore, (228 million dollars) ÷ (6 months) = -38 million dollars.
So the answer is A) -38 million dollars.
48 – (−12) =

B -60-60
C -36-36
D 6060
48 - (-12) can be simplified as follows:
= 48 + 12 (two negative signs cancel out)
= 60
So the answer is D) 60.
10 − (−10) + 8 − 12
Responses
A −4−4
B 1616
C 44
D 13
10 - (-10) can be simplified as follows:
= 10 + 10 (two negative signs cancel out)
= 20
Now, the expression becomes:
20 + 8 - 12 = 16
So the answer is B) 16.
Emma is thinking of subscribing to an e-magazine. The subscription price for one year is $5 per month, which will be withdrawn from Emma's checking account. Express the amount that will be withdrawn for the annual subscription, as an integer.
Responses
A $15$15
B -$5-$5
C $30$30
D -$10-$10
E -$60-$60
The annual subscription price is $5 per month for 12 months, so:
Subscription price = $5/month x 12 months = $60
However, the question asks for the amount that will be withdrawn, which is the same as the subscription price, but with a negative sign (since the money will be withdrawn from Emma's account).
Therefore, the amount that will be withdrawn for the annual subscription is -$60.
So the answer is E) -$60.
