How do we add 863+(-691)=?

Question

not sure how to work this out

Answer 1

The -691 changes the + sign to a -, so it would be 863-691, which equals 172.

Answer 2

Since a pos+ and a neg- equals a negative.

therefore 863 + (-691) = 863 - 691

                                       = 172

Answer 3

since,'+'(*)-='-'. u can just subtract 691 from 863 which is 172.

Answer 4

863+(-691) is the same thing as 861-691.

Answer 5

when you are adding something negative you just subtract. the answers 172.

Answer 6

863+(-691) here we are performing two operations they are multiply '+' sign and '-' sign which results in '-' sign then substracting 691 from863



   863+(-691)=863 (+*-) 691=863-691=172

Answer 7

Is this a numerology question?  If it is, then 8+6+3=17=8

-691 = -7

8+ (-7) = 1

Just throwing in a spanner to your calculations, but technically if it is mathematical question, I would think that the answer would be 863 -691 = 172

Answer 8

just subtract 691 from 863

Answer 9

when a plus sign is next to a minus sign, both turn into a single minus sign

so 863 + - 691

= 863 - 691

= 172

it also works when other plus and minus signs are together

- - = +

+ + = +

- + = -

+ - = -

Answer 10

The way I do it is take 863 minus positive 691 and that is your answer because that is the difference between them. That may not be the correct way though. You could always use a calculator :o)

Hope I helped!
