What is 8 minus negative 11?

Here we will not only give you the answer to 8 minus negative 11, but also explain how we got the answer.

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 observation:

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 8 minus negative 11, we are subtracting a negative number and we go to the right. Specifically, we go from +8 to +19 on the number line.

Here is 8 minus negative 11 in mathematical terms with the answer:

8 - (-11) = 19

You may already know that minus minus equals plus or that 8 minus negative 11 is the same as 8 plus 11, but we hope that this page explained the underlying mathematical reason for the answer.
