Leo weighs his macaroni
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Leo begins his multiplications with "1 times 1 equals 1". Instead of actually counting the individual pieces of macaroni, he uses a weighing scale to weigh out 100g of macaroni, and puts that in the cup. There is no discernible pattern to the multiplications he chooses to solve, skipping around from "1 times 100 equals 100", to "100 times 1.1 equals 110", to "2 times 20 equals 40", to "5 times 2.5 equals 12.5", and then "1 times 666 million is 666 million". He weighs out a 10g portion of macaroni and counts how many pieces are in that (130), and then multiplies that by 10 to estimate how many he has already put in the cup (1,300), then adds his extra 130, reaching an estimate of 1,430. In the studio, Bård points out that Leo was the only one to count his macaroni like a drug dealer. He notes that Leo only actually managed to count 130 pieces of pasta, and Olli confirms that his weight-based estimate of the total number of pieces in the cup at the end was incorrect. They therefore permit him the 130 pieces that he actually counted, which earns him second place.
