What is 14 minus negative 7?




Here we will not only give you the answer to 14 minus negative 7, 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 14 minus negative 7, we are subtracting a negative number and we go to the right. Specifically, we go from +14 to +21 on the number line.

Here is 14 minus negative 7 in mathematical terms with the answer:

14 - (-7) = 21


You may already know that minus minus equals plus or that 14 minus negative 7 is the same as 14 plus 7, but we hope that this page explained the underlying mathematical reason for the answer.
