- Wait.... I'm confused..... What does 2L means again?(7 votes)
- 2L just means 2 liters. L is short for liters, the basic metric measurement for amounts of fluid, and 2 liters (2L) is a standard size for a large bottle of soda.(9 votes)

- So most of that word problem was just pointless? Then why does the creator even put it in there?(4 votes)
- So you are able to find out what information you might need to use yourself. In real world problems, you often have a lot more information available than you need so it's an important skill to teach.(3 votes)

- what is repeated addition(2 votes)
- Repeated addition is a type of process in which you add equal groups multiple times. Multiple means many times.

Have a blessed and wonderful day(6 votes)

- At1:11what is a " liter?"(1 vote)
- a metric unit of capacity, formerly defined as the volume of 1 kilogram of water under standard conditions, now equal to 1,000 cubic centimeters (about 1.75 pints).(7 votes)

- i dont get that its going to be 6+6+6+and the rest(2 votes)
- It's not 6 you're adding a bunch of times, it's 2!

"6 bottles of soda were used for a picnic last week" has nothing to do with LITERS, nor does it have to do with how many liters are in each bottle. Just remember to cross out EVERY SENTENCE (the ones on the right) that doesn't have to do with the QUESTION.(4 votes)

- Did you draw the sodas SAL?(3 votes)
- he did read the description(1 vote)

- Jack has 5 soda cans and he gives 5 away how many soda cans does jack have left(1 vote)
- Jack has 0 soda cans because he had 5 but he gave away 5. So for this we do subtraction, and 5-5=0 :D

Hope you have a wonderful day(5 votes)

## Video transcript

So we're asked, "how many liters of
soda do we have for the party?" And they give us all of this other
information. I encourage you to pause this video
and think about which of this information you actually need to answer this first
question and then try to answer the question: "How many liters of soda do we have
for the party?" So pause now. Let's look at this information: "20 people are coming to the party."
This doesn't let us know how many liters we actually have. So we know we can ignore this. "We have purchased 5 bottles of soda for the party."
Well, this seems useful - we're going to have 5 bottles of soda. So that's 1... 2... 3.... 4.... and 5 bottles of soda.
That's this piece of information right over here. If only we now knew how much soda is in each bottle. "The party will last for 3 hours." This has nothing
to do with how many liters of soda we have. "Each bottle has 2 liters of soda." This
is interesting. This is 2 liters... this is 2 liters... this is 2 liters...
this is 2 liters... and that is 2 liters. If we wanted to figure out the total number
of liters of soda we have, We have 5 bottles, and each of them are
2 liters each. So we have 5 times 2 And what is that equal to? 5 times 2 is the same thing as
2 plus 2 plus 2 plus 2 plus 2 You have five 2's added together.
Let me write this down... Which is equal to: 2, 4, 6, 8, 10.
5 times 2 is 10. We have 10 liters of soda for the party.
We're able to answer it without even looking at this last one. This last one tells us how
many bottles of soda we had for the picnic last week. which doesn't seem related at all
to our current party.
