|SAT Problems: Unusual Symbols
|Since an unusual symbol is always defined in the problem,
read the problem two or three times to find the definition.
Try this example:
For all integers, let x be defined as the integer squared
and let y be defined as the integer cubed.
(A) x is always positive
(B) y is always negative
(C) x + y is always positive
(D) x + y is always negative
(E) none of the above
Solve: If x is 1, 2, 3, or -1, -2, -3, it is positive, but
since zero is an integer, x could be zero.
If y is 1, 2, 3, it is positive; if y is -1, -2, -3 it is negative; but
since zero is an integer, y could be zero.
Answer: Since zero is an integer, either x or y could be zero.
The answer is (E) none of the above
SAT TIP: Think of positive values, negative values, and zero.
