What is the rule for adding and subtracting negative numbers?
The Rules:
| Rule | Example | |
|---|---|---|
| +(+) | Two like signs become a positive sign | 3+(+2) = 3 + 2 = 5 |
| −(−) | 6−(−3) = 6 + 3 = 9 | |
| +(−) | Two unlike signs become a negative sign | 7+(−2) = 7 − 2 = 5 |
| −(+) | 8−(+2) = 8 − 2 = 6 |
Why is minus a minus a plus?
This is in fact the reason why the negative numbers were introduced: so that each positive number would have an additive inverse. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.
What happens when you subtract a negative from a positive?
Rule 4: Subtracting a negative number from a positive number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you’re adding a positive, so you have a simple addition problem.
Do 2 negatives make a positive when subtracting?
If you subtract a negative number, the two negatives combine to make a positive.
What happens if you subtract a negative from a negative?
Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. On the number line, it starts at -2.
Why do two minuses make a plus?
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.
What’s a positive plus a positive?
ADDITION/ SUBTRACTION: ):( Positive number plus a positive number, add the two numbers, and it equals a positive number. (+) Positive. Plus+ Good Guy.
What’s a negative times a positive?
Rule 2: A negative number times a positive number equals a negative number. When you multiply a negative number to a positive number, your answer is a negative number. It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.
Why does multiplying by a negative reverse the sign?
When you multiply both sides by a negative value you make the side that is greater have a “bigger” negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.
Do you flip the inequality sign when subtracting?
Adding the same number to each side of an inequality does not change the direction of the inequality symbol. If a < b, then a – c < b – c. Subtracting the same number from each side of an inequality does not change the direction of the inequality symbol.
What is negative plus 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. For example, -3 + (-2). This reads “negative three plus negative 2”. Then we subtract 2. The answer is -5.
Why does a negative and a negative make a positive?
When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.
How do you teach subtracting negative numbers?
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.
What are the rules of subtracting integers?
Steps on How to Subtract Integers
- First, keep the first number (known as the minuend).
- Second, change the operation from subtraction to addition.
- Third, get the opposite sign of the second number (known as the subtrahend)
- Finally, proceed with the regular addition of integers.
What do two positives make?
When We Multiply:
| Example | ||
|---|---|---|
| × | two positives make a positive: | 3 × 2 = 6 |
| × | two negatives make a positive: | (−3) × (−2) = 6 |
| × | a negative and a positive make a negative: | (−3) × 2 = −6 |
| × | a positive and a negative make a negative: | 3 × (−2) = −6 |
Is a negative times a negative a positive?
A simpler algebraic proof Similarly, we can prove that a negative times a negative is a positive. Since we know that −ab is negative, and the sum of these two terms is 0, therefore (−a) × (−b) is positive.
