Example Question #101 : Negative Numbers
The division of two negative numbers yields a positive result.
Example Question #102 : Negative Numbers
In a division problem, if the signs are different (one is negative and one is positive), the answer is negative.
Example Question #696 : Hspt Mathematics
The temperature has been falling an average of per hour. If the temperature at 1:00 A.M. is , then what will be the weather at 6:00 A.M.?
If the temperature is dropping for hours (1:00 A.M.-6:00 A.M.), then that would be represented as:
If the temperature at 1:00 A.M. is then:
Subtract and take the sign of the higher absolute value.
The sign of the higher absolute value, which is , is negative.
The temperature is at 6:00 A.M. is the correct answer.
Example Question #697 : Hspt Mathematics
The rules for adding integers with different sign is to subtract the absolute value of these numbers, and then take the sign of the higher of the two numbers.
Because has the larger absolute value and is positive, the correct answer is:
.
Example Question #103 : Negative Numbers
The order of operations is PEMDAS, or (1) Parentheses (2) Exponents (3)Multiplication/Division (4) Addition/Subtraction.
First, we need to cube the quantity .
Now we are left with .
Subtracting a negative is the same as adding a positive. So we can rewrite this as
