1 - -1 = 2
1 + 1 = 2

is subtracting -1 the same as adding 1?

no, it's not.


think of the number line as having +∞ and -∞ on each side



if you have ∞ + 1 on the positive side and ∞ on the negative side then you have 1.


if you subtract -1 you get
∞ + 2, ∞ - 1
if you add 1 then you get
∞ + 3, ∞

both
∞ + 3, ∞
and
∞ + 2, ∞ - 1
equal three

but the are not the same number


does this make sense?

come on!


it's a simple number line concept explaining why 2 - -1 =/= 2 + 1 even though you get the same result.

no it's just a double negative which makes it a positive

"no it's just a double negative which makes it a positive"
don't be so sure

there are two options:
negatives cancel one another and produce an affirmative
or
double negatives intensify the negation

i feel like this is making a simple concept unnecessarily complicated.... in basically any normal use, 2+1 and 2-(-1) are exactly the same thing

that's what you do in order to prove something is true
