Answer 1

what is -1 + 6

Answer 2

any ideas?

Answer 3

@jim_thompson5910 - -5?

Answer 4

-5

Answer 5

think of it like this

Answer 6

you are in debt 1 dollar (represented by -1)

you then find 6 dollars somewhere

how much money do you have overall now?

Answer 7

5

Answer 8

oh and once you find the 6 dollars you have to pay off that debt immediately

Answer 9

yep so that means -1 + 6 = 5

Answer 10

nice explaining jim :)

Answer 11

so we go from

-1+6+(-7)

to

5 + (-7)

Answer 12

thanks kelliegirl33, I really appreciate it

Answer 13

-2

Answer 14

to evaluate 5 + (-7), use the idea of money again

you have 5 dollars, then you spend 7 dollars and you'll end up 2 dollars in debt

so good, 5 + (-7) = -2

Answer 15

overall,

-1+6+(-7) = -2

Answer 16

so if I had to show work on my paper how would it look?

Answer 17

basically you could add the numbers like we did where we added them in pairs and we broke up the problem

if you had more numbers, you just keep the same basic pattern going

ex:

1+2+3+4

3+3+4 ... add the first pair

6+4 ... add the next pair

10 ... you keep adding pairs until you're done

Answer 18

make sense?
