5. Consider the following example: Two groups of high school students estimated, within 5 seconds, a numerical expression that was written on the blackboard. One group estimated the product 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 while another group estimated the product 1 x 2 x 3 x 4 x 5 x 6 x 7x 8. To rapidly answer such questions, people may perform a few steps of computation and estimate the product by extrapolation or adjustment. Because the result of the first few steps of multiplication (performed from left to right) is higher in the descending sequence than in the ascending sequence, the former expression should be judged larger than the latter. Both predictions were confirmed. The median estimate for the ascending sequence was 512, while the median estimate for the descending sequence was 2,250.
