Transcript Keywords for Multiplication

We’re here at the Sandstone Aquifer for the Strength Factor Contest. Let’s meet the contestants.

We have animals from far and wide competing in feats of strength: a gorilla vs a vulture competing in the deadlift an elephant vs a tiger in a carrying contest and an ox vs a dung beetle in a contest of pushing power. To judge the winners, the judge will compare how much weight each of the contestants can lift with their respective body weight. The contestants with the greatest strength factor in their competition will be crowned the victor. Our judge, David Hasselsloth, will have to perform multiple calculations to determine the relative strength of the two competing animals. Since this is a contest of relative strength, the judges need to know the keywords for multiplication.

In multiplication problems, you’re given a multiplicator and a multiplicand. When we multiply these together, we get the product, which is the answer. Thanks to the commutative property of multiplication, it doesn’t matter the order in which things are multiplied together so the multiplicator and multiplicand are commonly referred to as factors. There are many ways to represent multiplication: vertically, like this or horizontally like this: Each of these methods of representation mean the same thing, so which one you use is your choice.

David looks at the results from the deadlift competition. Kong weighs 350 lbs. and registered a strength factor of 10! <so if you multiply those together, that means he lifted 3500 lbs! To match or beat Kong's result, Griff has to register a strength factor of 10 or higher. Unfortunately, Griff only managed to lift 4 times, or quadruple, his body weight. Griff weighs in at 25 lbs., and registering a strength factor of 4 means he lifted 100 lbs. David Hasselsloth determines Kong to be the deadlift champion.

In the closest competition of the day, Elly and Tiggy squared off in the static carry competition. Elly was able to carry 1.5 lbs for every 1 lb. of body weight. Since she weighs 13,000 lbs., Elly was able to carry 19,500 lbs!!! That’s gonna be tough to beat! Tiggy, however was up to the challenge and was able to carry double her bodyweight! David Hasselsloth checks the records and sees that Tiggy weighed in at 370 lbs. Judge Hasselsloth multiplies Tiggy’s weight by two and comes up with 740. The honorable Judge judges Tiggy’s try to be greater than Elly’s and declares Tiggy the winner of this event. Because Tiggy's multiplicand is two compared to Elly's multiplicand of 1.5.

Beetle Dungee elects to go first in the push-power competition. Going. Still going. Whoa…PER ounce of body weight…Beetle Dungee pushed over 1,100 ounces!!! He’s clearly the winner! A weight of only 0.97 oz. and the GREATEST strength factor of the competition - 1,141 times his bodyweight!!! Oxy’s so dejected that he doesn’t even ATTEMPT a pull!

Before we see the awards ceremony, let's review some keywords we used for multiplication: The multiplicator and multiplicand equal the product. Smaller pieces of the products are called factors and some trigger words that tell you to use the multiplication operation are: times, quadruple, for every, double, and per. So when we see or hear these words, we know we need to multiply. It's all over! Beetle Dungee is declared the winner of the Strength Factor contest! And he humbly receives his crowned and holds his ball of dung up in victorious triumph. Oops…I guess he's a little ticklish!
