A positve number subtract a negative number equals what?

It would equal a positive number.

2 - (-4) = 6

It would equal a positive number.

2 - (-4) = 6

ok..to give you a more clear view lets take the example!

a positive number = 7

a negative number = -3

now subtraction.....

7 - (-3)

when two minus come together....lightening occrs and the two bad brothers become one good team thats a plus sign!

so

= 7 + 3

= 10

did that help?

you can think of positive numbers as hot numbers and negative ones as cold numbers.

if you take cold air out of a room then the room gets hotter.

so

6 - - 2 = 6 + 2 = 8

thats a really clever example melody!

Well Rosala, It just sounds like a lot of hot air to me. :)
