### HideShow timer Statistics

can someone help me with this question on OG11 PS#20.

Of the five coordinates associated with points A,B,C,D and E on the number line above, which has the greatest absolute value?

(A) A
(B) B
(C)C
(D)D
(E)E

The OG guide says the answer in A but then why isnt it E because that is also 2 away from 0

Thanks

OG says:
The distance between the number and zero is called absolute value.
Absolute value of a non zero number is always positive

hence clearly distance b/w 0 and -2 = 2 units is the greater than ditance b/w 0 and other points on the number line.

broncos222,

you might be having an older version of the OG. The link below directs you to the corrections that has been implemented in the later versions.

If the original figure was correct and E was equal to 2 then AC = CE = 2. Thus, what you mentioned would be incorrect
