I’ve got five numbers

here, and the goal is to order them from

least to greatest. And it might be obvious to you

that all five of these numbers are negative numbers. So let’s just think about

which of these is the greatest number. And you might be tempted

to say oh, well, you know, if these were all positive,

40 would be the greatest. So you might be tempted to say

negative 40 is the greatest. But you have to realize what

the negative is telling you, and to think about that. Think about if these

were your dollar amounts in your bank account. Would you rather have negative

$40 in your bank account or negative $7 in

your bank account? Negative 40 means that

you owe the bank $40. So it’s 40 less

than having nothing. Negative 7 would mean that

you owe the bank only $7. So it’s actually the

case that negative 40 is less than negative 7. And out of all of these numbers,

it is the least of all of them. So negative 40 is the very

least that you could do. That’s the least amount of

money that you would want out of these comparisons

in your bank account, or the smallest amount of money. You owe the bank $40. Not only do you have nothing,

you owe the bank $40. Then the next smallest

number would be negative 30. And then the next smallest

after that would be negative 25. And then the next smallest

after that would be negative 10. And then finally, the greatest

of all of these numbers– and I will do it in pink–

the greatest of all of these numbers is negative 7. And if it’s still

not obvious to you, you could also think of

them in temperature terms. Which of these is the

coldest temperature, whether you’re talking

about Celsius or Fahrenheit? Negative 40 would be

the coldest temperature. Negative 7 would be the

warmest temperature. There would be the most heat

in the air at negative 7. Another way to think about it

is we could draw a number line. So let’s draw a number

line right over here. If this is a zero, and we could

put maybe positive 7 up here. Positive 7 isn’t one

of these numbers, but then we could plot

all the other numbers. So this right here

might be negative 7. If that’s negative 7, then

maybe this right over here would be negative 10. Notice we go further and

further to the left of zero. And then we go a little

bit further to the left. We get negative 25. A little bit further to the

left than that is negative 30. And then you go even

further to the left and you get to negative 40. So if you think of it this

way, the least of these numbers is the one that’s furthest to

the left on the number line, and the greatest is the one

that’s furthest to the right.

It's a new teacher. Still good. π

lol i have to watch this for my homework for today

Niggative Numbers.

Niggative Numbers.

He is really smart!

Hahahahahahahahaajajaj

Great you can teach the whole world, I learned a numerous amount of things=) thanks great stuff

Thank you so much now I won't have to struggle in my HomeWork!

it worked so well i got a A on a test π

Thanks it really helped me >:D

this video helped me on my HW

i hate math

Homework is so hard but this helps me thanks

Iβm preparing for middle school because Iβm going to be in advanced math, and this helped me so much. Thank you. I subbed your channel and liked your video. Your the only person I trust with math.:D

M=mental

A=abuse

T=to

H=humans

Math: mental abuse to humans

This helped thx

what are the ones with the lines next to them though
