When you'd subtracted a positive number, you'd moved to the left. Adding and Subtracting Integers. Now, if you're adding a negative number, you can regard this is pretty much the same as when you were subtracting a positive number, if you view "adding a negative" as adding to the left. That is, by plus-ing a minus, you're adding in the other direction.

Negative 4 minus negative 2

Subtracting positive numbers, such as 4 - 2, is easy. When we subtract negative numbers or subtract negative numbers to positive numbers, it gets more complicated. Here are some simple rules to follow when subtracting negative numbers. For example: this is what you have learned before. So, instead of subtracting a negative, you are adding a positive.

It looks like this:, negative 4 minus negative 2. When you're just starting out, you may find it helpful to convert "minus [some number]" to "plus the minus of [that number] ", which can make it easier to keep track of where those "minus" signs need to go.

This is, by the way, an example of a "proof by contradiction", wherein you assume something that is the opposite of what is true [in this case, assuming that the minus of a minus is another minus], show that this assumption leads to a contradiction of known good information [namely, that zero equals two], and thereby prove that the assumption was false, so the opposite is true [namely, that the minus of a minus is a plus]. No cop is gonna buy the "but it's for my math class" excuse. All Rights Reserved. I'll start by converting the minus of minusses to plusses, and the minusses to plusses of minusses.

If you add three double-hot cubes add three-times-positive-two , the temperature goes up by six. The analogies above aren't technical explanations or proofs, but I hope they make the "minus of a minus is a plus" thing seem a bit more reasonable.

If you remove a hot cube subtract a positive number , the temperature goes down. What does negative 2 minus 4 equal? In a sense, the two minuses "cancel" each other off; think of drawing a vertical line through both "minus" signs, turning them into "plus" signs:. Positive 3 plus negative 5 minus negative 2 minus positive 4 is equal to When you'd subtracted a positive number, you'd moved to the left. At step C , I applied the wrong assumption that the minus of a minus should be another minus rather than a plus. In practice, yes, you will be drawing an actual vertical line through the "minus" signs to create the "plus" signs.
