Moving Sum

**Moving Sum** is a challenge of logical intelligence on *Canada's Smartest Person*.

## Description

*Retrieved from CBC.ca*

Moving Sum focuses on solving a series of mathematical problems under pressure - with a visual twist. The numbers float around the screen, so the competitors need to make split second decisions on how to follow the numbers spatially to process the equations. The test resembles the kind of problems pilots need solve, as they process data from many sources simultaneously. With each question the equations become more and more difficult.

On the screen, the competitors will see a math problem and a series of numbers moving below it. They'll have just a few seconds to use the numbers to solve each equation. The most correct answers takes the challenge.

## Episode 101

Moving Sum was the sole challenge of logical intelligence and the first challenge overall. Jeff Douglas explained to the viewers the instructions and how they could play along with the contestants on the Canada's Smartest Person app. Jessi Cruickshank explained to the contestants that the contestant in 1st place would earn 5 overall points, the contestant in 2nd place would earn 3, the contestant in 3rd place would earn 2, and the contestant in last place would earn 1.

In the first round, the contestants had to determine the correct sum of all the numbers that appeared on the screen in four different sets. The first set of numbers consisted of 2, 4, 4, 7, 7, and 8, which result in 32 as a sum of all the numbers (2+4+4+7+7+8=32). The second set of numbers consisted of 1, 3, 7, 8, 9, and 9, which result in 37 as a sum of all the numbers (1+3+7+8+9+9=37). The third set of numbers consisted of 2, 2, 3, 4, 8, and 9, which result in 28 as a sum of all the numbers (2+2+3+4+8+9=28). The final set of numbers consisted of 1, 2, 2, 5, 6, 9, and 9, which result in 34 as a sum of all the numbers (1+2+2+5+6+9+9=34). Roselyn Kelada-Sedra got 2 correct answers, Kiel Lemmen got 3, Tova Sherman got 3, and Albert Tam got 4.

In the second round, the contestants had to determine either the correct sum of all the even numbers that appeared on the screen or the correct sum of all the odd numbers that appeared on the screen in four different sets. The first set of numbers consisted of 2, 2, 3, 4, 5, 7, 8, and 9, which result in 16 as a sum of all the even numbers (2+2+4+8=16). The second set of numbers consisted of 1, 1, 4, 5, 6, 7, 9, and 14, which result in 23 as a sum of all the odd numbers (1+1+5+7+9=23). The third set of numbers consisted of 1, 3, 4, 5, 6, 7, 8, 9, and 12, which result in 30 as a sum of all the even numbers (4+6+8+12=30). The final set of numbers consisted of 2, 3, 3, 4, 4, 6, 9, 9, and 10, which result in 24 as a sum of all the odd numbers (3+3+9+9=24). Roselyn got 3 correct answers, Kiel got 4, Tova got 4, and Albert got 4.

In the final round, with the exception of the final set of numbers, the contestants had to determine both the correct sum of all the even numbers that appeared on the screen and the correct sum of all the odd numbers that appeared on the screen and then correctly perform another operation using those two sums as numbers. The first set of numbers consisted of 1, 5, 6, 6, 6, and 6, which result in 4 as a quotient of the sum of all the even numbers divided by the sum of all the odd numbers ((6+6+6+6)/(1+5)=4). The second set of numbers consisted of 1, 5, 5, 6, 6, 6, and 6, which result in 13 as a difference of the sum of all the even numbers minus the sum of all the odd numbers ((6+6+6+6)-(1+5+5)=13). The third set of numbers consisted of 2, 6, 6, 6, 9, 9, and 9, which result in 7 as a difference of the sum of all the odd numbers minus the sum of all the even numbers ((9+9+9)-(2+6+6+6)=7). The final set of numbers consisted of 3, 4, 6, 7, 8, 10, 13, which result in 23 as a sum of all the prime numbers (3+7+13=23). Roselyn got 0 correct answers, Kiel got 2, Tova got 3, and Albert got 3.

In total, Roselyn got 5 correct answers, Kiel got 9, Tova got 10, and Albert got 11. Therefore, Albert was awarded 5 overall points for finishing in 1st place, Tova was awarded 3 for finishing in 2nd place, Kiel was awarded 2 for finishing in 3rd place, and Roselyn was awarded 1 for finishing in last place.

As for the public, the demographic of individuals aged 18-49 performed the best with an average percentage score of 32%, the demographic of individuals aged 50 and over performed the second-best with an average percentage score of 31%, and the demographic of individuals aged 17 and under performed the worst with an average percentage score of 17%. Also, it was revealed that Jeff himself had received a percentage score of 77%. However, the scores for the public are calculated differently than the scores for the contestants.

## Episode 208

Moving Sum was the sole challenge of logical intelligence and the sixth challenge overall. Jessi Cruickshank explained to the contestants that the contestant in 1st place would earn 4 overall points, the contestant in 2nd place would earn 3, the contestant in 3rd place would earn 2, and the contestant in last place would earn 1. She then explained to the viewers the instructions and how they could play along with the contestants on the Canada's Smartest Person app.

In the first round, the contestants had to determine the correct sum of all the numbers that appeared on the screen. The set of numbers consisted of 2, 3, 5, 7, 11, and 14, which result in 42 as a sum of all the numbers (2+3+5+7+11+14=42). All four contestants answered correctly.

In the second round, the contestants had to determine both the correct sum of all the even numbers that appeared on the screen and the correct sum of all the odd numbers that appeared on the screen and then correctly divide the former sum by the latter sum. The set of numbers consisted of 1, 5, 6, 8, 8, and 8, which result in 5 as a quotient of the sum of all the even numbers divided by the sum of all the odd numbers ((6+8+8+8)/(1+5)=5). Tim Blais, Jason Vander-Hoek, and Katy Warren answered correctly while Anthony Craparotta failed to do so.

In the third round, the contestants had to determine both the correct sum of all the even numbers that appeared on the screen and the correct sum of all the odd numbers that appeared on the screen and then correctly multiply the former sum by the latter sum. The set of numbers consisted of 1, 2, 2, 3, 3, 3, and 4, which result in 80 as a product of the sum of all the even numbers times the sum of all the odd numbers ((2+2+4)X(1+3+3+3)=80). Again, Tim, Jason, and Katy answered correctly while Anthony failed to do so.

In the fourth round, the contestants had to determine both the correct sum of all the even numbers that appeared on the screen and the correct sum of all the odd numbers that appeared on the screen and then correctly subtract the former sum by the latter sum. The set of numbers consisted of 1, 2, 5, 5, 8, 8, and 8, which result in 15 as a difference of the sum of all the even numbers minus the sum of all the odd numbers ((2+8+8+8)-(1+5+5)=15). All four contestants answered correctly.

In the fifth round, the contestants had to determine both the correct sum of all the odd numbers that appeared on the screen and the correct sum of all the even numbers that appeared on the screen and then correctly subtract the former sum by the latter sum. The set of numbers consisted of 4, 4, 4, 4, 7, 9, and 9, which result in 9 as a difference of the sum of all the odd numbers minus the sum of all the even numbers ((7+9+9)-(4+4+4+4)=9). Anthony and Jason answered correctly while Tim and Katy failed to do so.

In the final round, the contestants had to determine the correct sum of all the prime numbers that appeared on the screen. The set of numbers consisted of 3, 4, 6, 7, 8, 10, and 11, which result in 21 as a sum of all the prime numbers (3+7+11=21). Tim and Jason answered correctly while Anthony and Katy failed to do so.

In total, Tim got 5 correct answers, Anthony got 3, Jason got 6, and Katy got 4. Therefore, Jason was awarded 4 overall points for finishing in 1st place, Tim was awarded 3 for finishing in 2nd place, Katy was awarded 2 for finishing in 3rd place, and Anthony was awarded 1 for finishing in last place.

As for the public, the top performers, by percentage score, were Adi of Montreal, Quebec, with 98%, Katy Fralick of Dartmouth, Nova Scotia, with 98%, Elisha Ricci of Georgetown, Ontario, with 98%, emistry4 of Toronto, Ontario, with 98%, Daniel Wu of Waterloo, Ontario, with 98%. However, the scores for the public are calculated differently than the scores for the contestants.

### Summary of Results

 **1st** | **Jason Vander-Hoek** | 6
