Is it possible for 2+2 to not equal 4?

Question

There can't just be one form of math, it is possible to use different forms of algebra and geometry right?

Answer 1

no math is a universal language 2 + 2 = 4. You cant create mass so if you have two grams and add two more grams you cant have 5 grams, its not possible.

and if someone brings out the 1984 responce in theory if everyone aggreed to count 1, 2, 3, 5,4 the 2 + 2 could equal 5 but that is just plain stupid and will never ahppen.

now you can make a straight line curve by placing it on a sphere 9think about that one for a while). 1 rule about that, it cant be on the "equator" or "prime meridian" then it wont "curve"

Answer 2

The answer is sure: Think of a 4 hour clock.
The numbers on the clock are 0,1,2,3.
Then 2+2 = 0 in this arithmetic.
Another model is going round the corners
of a square. Start at any corner and go clockwise
to the opposite corner(that's 2 moves).
Now advance 2 more spaces clockwise. You are back where
you started, so 2+2 = 0.
We can also construct a system in which
2+2=1. Use a 3 hour clock here.
Or, go round the vertices of a triangle.
You are so right--There are many different systems
with different answers in those systems.

Answer 3

it is not real. seem at this, a million. enable a and b be equivalent non-0 parts a = b , 2. Multiply by using via a a^2 = a^2 (ab) as a=b as this is your unique assumption. 3. Subtract b^2 , a^2 - b^2 = a^2 - b^2 , 4. element the two sides (a - b)(a + b) = (a - b)(a + b) , 5. Divide out (a - b) , a + b = a+ b , 6. observing that a = b , b + b = b + b , 7. combine like words on the left 2b = 2b , 8. Divide via the non-0 b 2 = 2 , for the reason that your unique assumption is a=b, then the mathematical representation ought to hold, and it does in accordance to the above.

Answer 4

Algebra and geometry are all forms of math but they all follow the same rules. 2+2 will always equal 4.

Answer 5

The meaning of the numbers can cause this to be untrue.

For exampe:
If you add a liter of water at 2 degrees to a liter of water at 2 degrees then you still have water at 2 degrees (but now 2 liters). So 2 degrees + 2 degrees = 2 degrees.

But as noted previously, with standard mathematical definitions at base 10, 2+2 = 4.

In binary, this would be 0010+0010 = 0100. Mathematically, this is the same as 2+2=4. Only different symbols are used.

Answer 6

if it is not base ten then yes
example if they were in base 3
3^0, 3^1
2 would equal 2, because 3^0=1 (so 2 would be 2)
but 4 would be 11 because 3^1=1, and 3^0=1, so 4 = 11
so 2+2 would equal 11

Answer 7

yes it is because 2+2=4 when your doing math in base 10 so if you did it in some other base then it would not equal 4.

Answer 8

If you are dealing with like items, 2+2 =4.
However, if you are dealing with unlike items 2+2 not =4. e.g. 2 biro+2pencil not equal to 4 biro nor equal to 4 pencil.
Let's go as low as posible to teach this fellow addition.

Answer 9

If you are adding a negative 2 to a positive 2, then the outcome would be zero. There is that circumstance. -2+2=0

Answer 10

it is possible; however, the formula used to give the answer has a small flaw that is sometimes overlooked (an order of operation).

For example this website shows some of these examples
