Negative 4 minus negative 2

The rules for adding and subtracting negative numbers works similarly to adding and subtracting positive numbers. When you'd added a positive number, you'd moved to the right on the number line. 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. In the same vein, if you subtract a negative that is, if you minus a minus , you're subtracting in the other direction; that is, you'll be subtracting by moving to the right. Graphically, it would be drawn as "an arrow from zero to nine, and then a 'negative' arrow going five units backwards":. Because you now have negative numbers off to the left of zero, you also now have the room necessary in order to complete this subtraction. View the subtraction as adding a negative 9 ; that is, draw an arrow from zero to five, and then a "minus" arrow that goes nine units backwards:.

If you remove a hot cube subtract a positive number , the temperature goes down. Here are some simple rules to follow when subtracting negative numbers. Best Answer. 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. You certainly don't want to use a number line for this. But how do you figure out which negative number is the answer? That is, by plus-ing a minus, you're adding in the other direction. So I won't give you a "proper" mathematical explanation of this "the minus of a minus is a plus" rule. For example: Say, we have the problem -2 — 3. Letting "good" be "positive" and "bad" be "negative", you could say:. These cubes come in two types: hot cubes and cold cubes. What does a positive minus a negative equal to?

But how do you figure out which negative number is the answer? Instead, you control the temperature of the stew with magic cubes. Visit Our Profiles. 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]. To get from the first starred line above to the second, I moved terms around to get all the plusses together and all the minusses together. 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:. Rule 2: Subtracting a positive number from a negative number — start at the negative number and count backwards. To add a negative, you're in "Drive" but, since you're facing the wrong way, you still plow into the car behind you.
