The Time Crunch In the "Mathematical Reasoning" test, you have about 70 seconds per question. You do not have time to do long division for everything. You need shortcuts.
Hack 1: The Last Digit Trick Question: 1234 × 5678 = ? Options: A) 7,006,650, B) 7,006,652, C) 7,006,653. Strategy: Don't multiply the whole thing! Just multiply the last digits: 4 × 8 = 32. The answer must end in 2. Look at the options. Only B ends in 2. You solved it in 5 seconds.
Hack 2: Estimation (The "Close Enough" Rule) Question: What is 49 × 21? Strategy: Round them to nice numbers. 50 × 20. 5 × 2 = 10, add two zeros = 1000. Look for the answer closest to 1000. (The real answer is 1029).
