In Math,when  1+1 is not  2?
602321
In binary, or base 2 numbers, 1+1=10. \n\nBase 2 is a number base where there are only 2 digits in the number system (symbols are usually 0 and 1), the number system we usually use is base 10 numbers (symbols are usually 0 1 2 3 4 5 6 7 8 9).\n\nin binary:\n0 = 0\n1 = 1\n2 = 10\n3 = 11\n4 = 100\n5 = 101\n6 = 110\n7 = 111\nand so on...

It's when you make mistake in addition. But I won't say the sum can't be put correctly but It can be made correct by changing the sign You could change the sign from + to - . Now can I have my ten points ? Please ???!

1+1 = 10 if you are counting in binary.\n\n1+1=0 with 1 carry over if you are counting in urinary.\n\nanything bigger than binary = 2.\n\n1+1 = 1 if you are talking logical (OR) also.\n\n1+1 = 2 at first then it becomes 3 then 2 again if you are talking about marriage and divorce.

Ummm, I'm not even sure what that means, but I'm guessing:\n\n(1 *1) + (1*1) + (1*1) \nerm...or, in sentence form one times one plus one times one plus one times one.

The answer is "i" because there is no number, that when mutliplied by itself, will give you -1.  Think about it: the only possible combination that would make sense is 1 X 1, which equals 1...not -1.

1(1)+0(2)+1(4)+1(8)+1(16)+0(32)+0(64)+0(128)+1(256)=\n1+0+4+8+16+0+0+0+256=\n285

its impossible because there needs to be either one less sign or one more number look:\n\nin a the order:\n2 * 4 - 6 + 8 /\n              ^there is an extra sign!!

False... y has to be 2...\n(3,2) is a solution, but not (3,1).

we need to multiply something by (x+1) so that the result would be x^2-1. but we know x^2-1 = (x-1)(x+1).\nso we have to multiply (x-1) with (x+1) to get x^2-1.

+/- 1\n\nThe answer is not 1, because -1 * -1 = 1 also.

"+" is called "plus."  2+2=4.\n"-" is called "minus."  4-2=2.\n"*" is called "times." 4*4=16.\n\nGot it now?

here we are talking about a  sequence , so we try to get the formula of the sequence than the result.\nBut the proposed solution that 1=5 it's completly  wrong

no \n3x-1>1 \n3x>2 \nx>2/3

1+1=2. That's it. The answer for everything else would be simply 42

No, it follows from 1+1 = 2\n\nWhich follows from 1+0 = 1\n\nBut that can be considered an amazing "fact".  In reality, it's an axiom - a definition.  One of the only true defintions that form the basis of mathematics.

bc when u have 2 and you take 4 away from it, you are negative 2--- think of it like this: 2-4=-2

by inspection I can understand another point will be...\n\n(0, 5) because if you add 1 to X you must add 2 to Y
