What do you get when you subtract a negative and a positive?
When taking a negative number minus a positive number, drop both minus signs and add the two numbers as if they were both positive; then attach a minus sign to the result.
When you add a negative and a negative Do you get a positive?
When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.
What does a positive and a negative make?
Multiplication and Division If two positive numbers are multiplied together or divided, the answer is positive. If two negative numbers are multiplied together or divided, the answer is positive. If a positive and a negative number are multiplied or divided, the answer is negative.
Do 2 negatives make a positive when multiplying?
Yes indeed, two negatives make a positive, and we will explain why, with examples!
What is the rule for subtracting negative numbers?
Subtracting a negative number is like adding a positive; you move to the right on the number line. Example 4: Subtract −4−(−7) . Start at −4 , and move 7 units to the right.
What is positive minus negative?
So, instead of subtracting a negative, you are adding a positive. Basically, – (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 – –4.
Does a negative cancel out a positive?
Subtracting a negative number from a positive number cancels out the negative signs and becomes simple addition. It makes the positive number more positive. When you subtract a negative number from another negative number, once again the negative signs cancel each other to become a plus sign.
What happens when you add a negative and a negative?
When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. This reads “negative three plus negative 2”. You need to ignore the plus sign and recognize that the second negative means you are subtracting that number.
When do you use a minus sign to subtract a positive number?
When we are subtracting a positive number from another positive number, we usually use the minus ‘-‘ sign. For example: 8 and 4 and both positive numbers (note the lack of the minus sign before either) and thus 4 is taking away value from eight.
What happens when you subtract a negative from a positive?
The process works similarly to adding and subtracting positive numbers. 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.
Can a number be a positive or negative number?

What happens when you have two negative signs?
