Step 2: Check for Shortcuts and Clues
Check both quantities for possible shortcuts and for clues as to how to proceed. Here are
three different features to look for:
If both quantities contain common numbers or other terms, you might be able to
simplify by canceling them. Be careful, though; sometimes you can’t cancel terms.
(See the strategies later in this chapter.)
If one quantity is a verbal description but the other one consists solely of numbers
and variables, you’re dealing with a Problem Solving question in disguise. Your
task is to work from the verbal expression to a solution, then compare that
solution to the other quantity.
If the centered information includes one or more equations, you should probably
solve the equation(s) first.
Step 3: Deal with Each Quantity
If the problem includes any centered information (above the two quantities), ask
yourself how the quantity relates to it. Then do any calculations needed.
Step 4: Consider All Possibilities for Unknowns (Variables)
Consider what would happen to each quantity if a fraction, negative number, or the
number zero (0) or 1 were plugged in to the expression.
Step 5: Compare the Two Quantities
Compare the quantities in ColumnsAand B. Select one of the four answer choices, based
on your analysis.
Step 6: Check Your Answer
If you have time, double-check your answer. It’s a good idea to make any calculations
with pencil and paper so you can double-check your computations before confirming the
answer. Also, ask yourself again:
- Did I consider all possibilities for unknowns?
- Did I account for all the centered information (above the two quantities)?
