Question

The greatest recorded temperature change in one 24-hr period occurred between January 23 and January 24, 1916, in Browning, Montana, where the temperature fell from 440F to -560F. By how much did the temperature drop?

Answer 1

To solve this, subtract 440 from -560.

Answer 2

have you done that?

Answer 3

Yes I come up with -120

Answer 4

wait, remember that subtracting a pos from a neg number you add them if they were positive

Answer 5

because 560-(-440) has two neg signs, you can cancel them into a plus

Answer 6

So it would be 120?

Answer 7

er no, it would be 560+440

Answer 8

ok so since they both have negative signs you add them and it would be 1000

Answer 9

something like that, your answer is correct, but also remember that subtraction is the difference- the amount of space between two numbers on a number line

Answer 10

but the 440 is positive and the 560 is negative, or am I reading that wrong?

Answer 11

yes, so its like this- -2 is on one side of the number line, and 5 is on the other side, so the distance between them (the difference) would be 7, right?

Answer 12

yes

Answer 13

so its basically that, but on a larger scale

Answer 14

so 440 is on one side of the line and -560 is on another part of the line , so that would mean you add?

Answer 15

basically

Answer 16

ok ty
