Details are as below.Formula for the perfect Christmas toy - calculator required - Telegraph

FormerCardiff UniversityDr. Cliff Arnall, a lecturer psychologist, has been known to have formulated equations that seek "the most happy day in a year" and "the most depressed day in a year". By the way, in the UK "The happiest day"On June 19,"Most depressed dayIt is January 24th, but this time Dr. Arnall announced is an equation for comparing the toy of a child's Christmas present candidate. It seems that each child will give different results, helping to pick the best toy for that child.

First of all, we evaluate the following six items for the present candidate toy with a full score of 5 points, and give out the total point (full score of 30 points).

■ Pi:Can you play alone?

■ Po:Can we play with everyone?

■ Cr:Do you develop creativity?

■ S:Do you encourage social exchanges?

■ U:Is there practicality?

■ H:Can I settle down to my brother or sister?

Next, how many hours per one time to play (T, Unit: hour) and the period until the child gets bored with that toy (L, Unit: month).

Finally, add the total of the previous score and the number multiplied by T and L, add the total to the price of the toy (C: Can be anything but divide the currency when comparing multiple toys by the square root of).

The formula is as follows:

(T × L + Pi + Po + Cr + S + U + H) ÷ √ C = total score

A toy with a high total score is more suitable for Christmas gifts and it is possible to compare scores for various toys with a known price or to use "inequalities" to say "how much a toy A price will be divided by toy B "Buy" "is also required to be asked.

Additional notes:There was a person who made a calculator so that it can be easily calculated on the browser. You can examine the score exactly.
