#Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Even in the case, what happens when you divide two negative numbers?

When you divide two negative numbers, the answer is always a positive number. For example, -4 divided by -2 equals 2. When both numbers are negative, the negatives cancel out, resulting in the answer always being a positive number.

Beside, why do two minuses make a plus? If a number is positive, the + is usually missed out before the number. So 3 is really (+3). Adding and multiplying combinations of positive and negative numbers can cause confusion and so care must be taken. Two 'pluses' make a plus, two 'minuses' make a plus.

Either, do you add two negative numbers?

Adding two negative numbers together? Just add the absolute value of each number together, put a negative sign in front, and you have your answer!

What is the rule for subtracting negative numbers?

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. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

What are the rules for negative and positive numbers?

The Rules:RuleExample
+(+)Two like signs become a positive sign3+(+2) = 3 + 2 = 5
βˆ’(βˆ’)6βˆ’(βˆ’3) = 6 + 3 = 9
+(βˆ’)Two unlike signs become a negative sign7+(βˆ’2) = 7 βˆ’ 2 = 5
βˆ’(+)8βˆ’(+2) = 8 βˆ’ 2 = 6

What do two positives make?

When We Multiply:Example
Γ—two positives make a positive:3 Γ— 2 = 6
Γ—two negatives make a positive:(βˆ’3) Γ— (βˆ’2) = 6
Γ—a negative and a positive make a negative:(βˆ’3) Γ— 2 = βˆ’6
Γ—a positive and a negative make a negative:3 Γ— (βˆ’2) = βˆ’6

Why is minus a negative plus a positive?

Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.

What are the integer rules for adding and subtracting?

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.

What's a negative times a positive?

How do you multiply and divide positive and negative numbers?

The rule for multiplying and dividing is very similar to the rule for adding and subtracting.
  • When the signs are different the answer is negative.
  • When the signs are the same the answer is positive.
  • When you multiply two numbers with sign the product is negative?

    When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative. When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.

    How do you add subtract multiply and divide negative numbers?

    What is the rule for subtracting 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 are negatives and positives called?

    Positive and negative numbers are all integers. Integers are whole numbers that are either greater than zero (positive) or less than zero (negative). For every positive integer, there's a negative integer, called an additive inverse, that is an equal distance from zero.
