10-12 is called one trillionth.
7x + 12 = 5x + 2 Subtract '12' from both sides Hence 7x = 5x -10 Subtract '5x' from both sides. 2x = -10 Divide both sides by '2' Hence x = -5 .
10 to the negative 12th power is equal to 1 divided by 10 raised to the 12th power. This can be simplified to 1 divided by 1 followed by 12 zeros, or 0.000000000001. In scientific notation, this would be written as 1 x 10^-12.

It depends on the value of those numbers. ---------------------------- You always get a positive number. "Subtracting a negative number" is the same as "adding a positive number" because the two negatives "cancel." If I do something like 10 - (-12), this is the same as 10+12, or 22 (positive).
12
If you mean when you subtract a negative from a positive what does it make? If so, you will get a positive answer. This is because the two negative symbols are basically multiplied, and if you multiply two negatives you get a positive, so a positive number minus a negative number becomes a positive number plus a positive number. 6 - (-5) = 11 2 - (-10) = 12 125 - (-15) = 140
10 - -12 = 22
2
You can first subtract 2 from 12 to get 10. Then when you bring 10 across the = sign, it becomes -10, so 42-10 is 32.
The sum of -10 and -2 is -12.
12 because the negative of the negative is positive
get them to have the same demoninator. like if you have 5/6-3/4 make it 10/12-9/12. then just subtract.
