What is the result when one positive counter is paired with one negative counter?
Zero Pair When one positive counter is paired with one negative counter.
How do you do positive and negative numbers?
Positive numbers are written with no sign or a ‘ ‘ sign in front of them and they are counted up from zero to the right on a number line. Any number below zero is a negative number. Negative numbers are always written with a ‘ ‘ sign in front of them and they are counted down from zero to the left on a number line.
How do I add integers with different signs?
Answer: The rules for adding integers with the different sign is to retain the sign of the absolute value of the bigger number, subtract the absolute value of the bigger number from the smaller number.
What is a zero pair and why is it important?
A zero pair is a pair of numbers that, when added together, equal zero. In other words, they cancel each other out.
What are two numbers that have a sum of 0?
| acute angle | An angle measuring less than 90º. |
|---|---|
| additive identity | The number 0 is called the additive identity because when you add it to a number, the result you get is the same number. For example, 4 + 0 = 4. |
| additive inverse | Any two numbers whose sum is zero, such as 3 and -3, because 3 + (-3) = 0. |
Does one positive and one negative make a negative?
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 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.
Do the counters represent positive or negative numbers?
Remember, the blue counters represent positive numbers and the red counters represent negative numbers. Perhaps when you were younger, you read 5−3 as five take away three. When we use counters, we can think of subtraction the same way.
What is the sum of a negative and a positive?
The sum of a positive and a negative integer is always negative.
