Question

How do you solve `6+(-6)`?

Answer 1

`6 + (-6) = 6 - 6 = 0`

Explanation:

Using a number line may help. Starting with a point '6' units to the right (a positive value), we "add" a negative value by moving to the left (-6). The result is:
`6 + (-6) = 6 - 6 = 0`

Answer 2

0

Explanation:

1) When adding a negative number it is essentially taking away the negative number if it had been positive:

`6+(-6) = 6-6`

• If this is the step you weren't confident with : Imagine you have $6 in the bank and you want to buy a ball for $6. Even though the bank would add the value of the ball to your account they would add a negative 6 dollars (-$6). So when adding this negative value, you would end up with a lower number, in this case, 0.

2) And as you know, anything minus itself is 0:

`6-6=0`

For future reference:

• plus minus (+-) or minus plus (-+) just mean minus (-)

• minus minus (--) or (plus plus) (++) just mean plus (+)
