Negative 1 minus negative 2 can be written as follows in mathematical terms:

(-1) - (-2)

That is a lot of negatives! With all the minus signs it may be confusing to figure out how to subtract a negative number from another negative number.

Don't dispair. We will explain how to solve negative 1 minus negative 2 so you understand the problem and can easily solve similar problems in the future.

Start by picturing a number line that goes to negative infinity on the left side of 0 and positive infinity on the right side of 0:

∞ ..... -3, -2, -1, 0, +1, +2, +3, .... ∞

Looking at the number line above, we can make the following observations:

Adding a positive number goes to the right.

Adding a negative number goes to the left.

Adding and subtracting cannot go in the same direction on a number line. Therefore, this must also be true:

Subtracting a positive number goes to the left.

Subtracting a negative number goes to the right.

Thus, with the problem negative 1 minus negative 2, we are subtracting a negative number and we go to the right. Specifically, we go 2 "spaces" to the right from -1 to +1 on the number line.

Here is negative 1 minus negative 2 displayed with the answer per the explanation above:

(-1) - (-2) = 1
