In a study by Ihle-Hansen et al. (2017), of 3,413 Norwegian participants aged 63–65, of whom 47% had higher education (over 12 years), under 5% of subjects scored 30/30 with a mean MoCA score of 25.3 and 49% scoring below the suggested cut-off of 26 points, leading the authors to suggest that "the cut-off score may have been set too high to ...

The product of two variables ranging from 90-99 will result in a 4-digit number. The first step is to find the ones-digit and the tens digit. Subtract both variables from 100 which will result in 2 one-digit number. The product of the 2 one-digit numbers will be the last two digits of one's final product.
For example, given a random seven-digit number, one may remember it for only a few seconds before forgetting, suggesting it was stored in short-term memory. On the other hand, one can remember telephone numbers for many years through repetition; this information is said to be stored in long-term memory.
