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.
for instance, What does a negative plus a negative equal?
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.
significantly, What happens if you subtract a negative from 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.
also What is the rule for adding and subtracting negative numbers?
The rule is: Adding a negative number is the same as subtracting the corresponding positive number.
What is negative plus a positive? Answer: Negative plus positive is negative or positive depending on the magnitude of numbers. Let’s understand the negative plus the positive number. Explanation: … If we add a negative integer, the value of the given number will decrease and if we add a positive integer the value will increase.

What happens when you subtract a negative from a positive?
Subtracting a negative number is the same as adding a positive number — that is, go up on the number line. … 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.
What is negative plus positive?
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 does a negative divided by a positive equal?
When you divide a negative number by a positive number, your answer is a negative number. As with multiplication, it doesn’t matter which order the positive and negative numbers are in, the answer is always a negative number. For example: -8 /2 = -4. And, the answer is still -4, when 8 is divided by -2.
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 are the rules of 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 |
What is the rule for adding and subtracting integers?
To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
Is 0 positive or negative integer?
Because zero is neither positive nor negative, the term nonnegative is sometimes used to refer to a number that is either positive or zero, while nonpositive is used to refer to a number that is either negative or zero. Zero is a neutral number.

Do 2 positives make a negative?
When multiplying or dividing with combinations of positive and negative numbers, you can simplify the process by first ignoring the signs (+/-) and just multiplying or dividing the numbers as if they were both positive. … When the signs of the two numbers are different, the answer will be negative.
What are the rules for negative and positive?
Two signs
- When adding positive numbers, count to the right.
- When adding negative numbers, count to the left.
- When subtracting positive numbers, count to the left.
- When subtracting negative numbers, count to the right.
Is a negative zero?
There is a negative 0, it just happens to be equal to the normal zero. For each real number a, we have a number −a such that a+(−a)=0. So for 0, we have 0+(−0)=0. However, 0 also has the property that 0+b=b for any b.
What is the greatest negative integer?
The greatest negative integer is the first negative integer from zero. The first negative integer from zero is one less than 0 and the number is – 1.
Is a negative integer?
A negative integer is a whole number that has value less than zero. Negative integers are normally whole numbers, for example, -3, -5, -8, -10 etc.
What are the rules for negative and positive integers?
RULE 1: The quotient of a positive integer and a negative integer is negative. RULE 2: The quotient of two positive integers is positive. RULE 3: The quotient of two negative integers is positive. If the signs are different the answer is negative.
What is a negative positive?
They can have one of two values: positive or negative. Positive integers have values greater than zero. Negative integers have values less than zero.
What is negative infinity?
The negative infinity in JavaScript is a constant value which is used to represent a value which is the lowest available. This means that no other number is lesser than this value. … Negative infinity, when divided by any positive number (apart from positive infinity) is negative infinity.
What is the negative of 13?
Step-by-step explanation:
Negative of -13 is -13 itself.
Is negative zero JavaScript?
JavaScript has a feature called signed zeroes, where positive zero ( +0 ) is the same as unsigned zero ( 0 ), but negative zero ( -0 ) is a different value, albeit one that behaves similarly. … This is because JavaScript implements the IEEE Standard for Floating-Point Arithmetic (IEEE 754), which has signed zeroes.
