Number Speed & Accuracy: Strategies

Three numbers are shown. The correct answer is the number furthest from the middle number.

Fast Method

1. Find the middle number.
2. Compute distances |L−M| and |R−M| in your head.
3. Select the larger distance’s endpoint.

Using the Arithmetic Aid

Visualize on the number line: the longer segment from the middle indicates the correct endpoint.

Avoiding Traps

• Numbers near the median can trick you—recheck sign/distance.
• Don’t waste time ordering all three; distances suffice.
