2 is prime, its only factors are one and itself.
(-1)+(-2)=(-3) (-1)(-2)=2
1 and 1/2 + 1 and 1/2
4 *2/2*1
256!
4 + 1 - 2 = 3
2 and 1
They are 1 x 2 assuming you mean whole numbers.
11 x 2 x 2 - 2
Yes, 1 1/2 + 1 1/2 = 2 2/2 or 3. The reason why are that real numbers and rational numbers are infinite and can add or subtract to make any number on the number line.
There are no real numbers that will answer this question, just imaginary numbers. The imaginary numbers are 1+sqrt(-2) and 1-sqrt(-2), which we normally write as 1+2i and 1-2i where i stands for the sort of (-1) (1+2i) + (1-2i) =2 (1+2i) * (1-2i) = 3 (note * stands for multiply)
