Taiga-4 x 3 = -12, and -4 + 3 = -1.
===================================
X + Y = -1
XY = -12
You want two numbers, X and Y. Multiplied together they will equal 12; if one of them is negative they will equal -12. They are one apart from each other, and if the larger one is negative their sum will be -1.
12 = 2 x 2 x 3, and the factors 4 and 3 are one apart from each other. If you make the larger one negative, it will fit both equations above.
The complexity of this question lies in its having a negative factor; if you ignore that at first, the answer is easy to see.
To solve it algebraically, you end up with: -X2 - X + 12 = 0; then you have to solve the quadratic.

How are the number sentences 12 times 1 equals 12 and 12 equals 1 times 12 the same?
These are the result of the fundamental laws of multiplication. In the real number system (and beyond), one is the identity of multiplication and that menas that 1*a = a*1 = a for all numbers a.
