so i suck with negitive numbers HELP!?

Question

Come up with some kind of real-world situation that is related to each of the following addition or subtraction problems.

1. -119 - -119
2. -119 - 119
3. -20 - 4
4. 50 - 30
5. 18 - (-7)
6. -10 + 12

9. -18 + -20
10. -50 - -65
11. 250 - 0.15 * 250 (that's 250 minus 0.15 times 250)
12. (1/3) * 120 (one-third times one hundred twenty)
13. 2 * -18.50 (2 times -18.50)
14. -83 / 3 (-83 divided by 3)

Answer 1

Here's a few to get you started.

2. bob's checking acct was 119 dollars overdrawn and another 119 dollar check cleared. what was the ending balance?

3. bob took out an atm withdrawl of 20.00 when he had no money in his account and the ATM took a 4.00 fee as well. What was his balance then?

4 bob wrote a 30.00 check on his balance of 50.00.

7. bob's account was 5 dollars overdrawn and was credited back a 3.00 fee.

13. after bob's two checks bounced, the bank assessed a fee of 18.50 for each of them. how much did that total to?

14. sam, bob, and bill share a checking acct. it's 83 dollars overdrawn. what is each man's share if the split it evenly?

Answer 2

Real World Applications

1. You are 119$ in debt and then you put 119$ towards this debt and you now owe nothing.

2. You are 119$ in debt and you purchase an item for 119$ therefore you are now 238$ in debt.

3. You owe 20$ to a friend and then you borrow another 4$ from this friend, so you now owe this person 24$

4. You have 50$ and you purchase something for 30$ so all you have left is 20$

5. You have 18$ in your wallet, and you go to a store to make a return - they give you 7$ back for your return so you now have 22$ in your wallet.

6. You are 10$ in debt and you pay 12$ towards this debt, so you have a credit of 2$

7. Same as 6

8. You are 30$ in debt and you purchase something for 14$, so you now are 44$ in debt

9. Same as 8

10. Same as 1

11. ??

12. You owe three people equal amount of 120$ so every person will recive (1/3) of the 120$

13. A persons debt was 18.50$ and they purchased the exact same thing for 18.50$ so their debt has now doubled.

14. If a person is 83$ in debt and they want to make three equal payments to get out of debt, each payment would be 27.67$.

Answer 3

well.. it seem that people got the answer but to make this short

if u add a negative number to a negative number, is like adding the actual number except is in negative for example
2. ) -119 - 119 think of it as (-119) + (-119) = -238

but if u add a negativer number to a positive number, is pretty much subtracting
7.) -5 + 3 is the samething as 3 - 5 = -2

however multiplying and dividing is different.
this pretty much is easy however

(-)(-) = (+)
(+)(-) = (-)

(-)/(-) = (+)
(+)/(-) = (-)

negative multiply/divide by a negative gives you a positive answer to matter what.
for example (-3)(-5) = 15 or (-15)/(-3) = 5
but if you multiply/ divide a negative to a positive, you will always get a negative.
for example
14.) (-83)/(3) = -27.67 or 2*-18.50 = -37

Answer 4

1. a bank account that is overdrawn by $119 = -$119. A refund would counter the negative balance by subtracting it. So an overdrawal of $119 minus that same overdrawal of $119 would be $0.

2. a bank account that is overdrawn by $119 = -$119. An extra over-withdrawal of $119 would cause that account to equal $238.

3. We have a vacuum of -20 psi. We take 4 more psi out of that atmosphere so that the vacuum equals -24 psi.

4. A barrel of 50 apples loses 30 due to a spill. So all that is left is 20 apples.

you get the jist right?

Answer 5

I did most of them and then I got bored. I hope that this helps you to understand how negative numbers are useful, and that it helps you to fill in the missing ones.

1. I am $119 in debt. I pay off the debt. This gives my total debt now.
2. I am $119 in debt. I take out a loan of $119. This gives my total debt now.
3. I am $20 in debt. I take out a loan of $4. This gives my total debt now.
4. I have 50 apples. I eat 30 of them. I have a stomachache. This gives the number of apples left.
5. Today the temperature is 18 degrees. Yesterday it was -7 degrees. This gives how many degrees higher the temperature is today than yesterday.
6. Yesterday, I spent $10 buying Christmas presents. Today my parents gave me $12 to mow the lawn. This gives the change in my amount of money since two days ago.
7. I am mountain climbing. I slip and fall 5 feet. Then I climb three feet upwards again. This gives the change in my elevation on the cliff.
8. The temperature falls 30 degrees. Then it falls 14 degrees. It is winter. Dammit. I hate winter. This gives the net change in the temperature, total.
9. I lost $18 on a bet yesterday. Then I lost $20 on a bet today. This gives the change in my net worth in the last two days.
11. I make $250 in gross pay. 15% of it is deducted for taxes. This gives the amount of my paycheck.
12. I go collecting seashells with two friends. We find 120 total and divide them equally among ourselves. This gives how many I get.

Answer 6

the first one is lacking component to it, i experience. to remedy it you should have an equivalent signal and a style on the different section. 2. Multiply the 9 with techniques from even with is contained in the parentheses. So 9m - 40 5 = 108. Then upload 40 5 to both section to get rid of the -40 5 on the left section. It will become 9m = sixty 3. Then divide both section with techniques from 9 to get rid of the 9. it is termed keeping apart the variable (the m). It will become m = 9. study that carefully and do precisely what it says on paper and also you should understand. 3. Do a similar element. First, multiply the 7 situations the (x - 2) to get 7x - 14 and then positioned that interior the equation. It will become 7x -14 - 4x = 10. carry mutually like words (the x's). It will become 3x - 14 = 10. (you've a positive 7x and a adverse 4x, see?) So now you should do what you probably did interior the severe one (yet utilising the numbers from this one). upload 14 to both section to get rid of the -14 on the left. 3x = 24, then divide with techniques from 3 to isolate the variable. x = 8. right it is a link that explains keeping apart the variable. :)

Answer 7

ok, let's see, when you add two negatives, just pretend you adding positive numbers, and of course the answer will be in negative.

When you subtract a negative, just pretend your adding that number as a positive number, for example: 4- -5=9

When you have an equation that has one negative number, and you divide it, it's ALWAYS negative

hopefully, it helped, and if I am guessing right, you are probably doing mid-terms, or finals! good luck!
