Rule 3: A negative number divided by a negative number equals a positive number. Two negative numbers form a positive number, so a negative number divided by a negative number is a positive number.
Rule 3: A negative number divided by a negative number results in a positive number. Example 3: This is also new and doesn’t seem very logical, but it’s a rule to keep in mind when dividing negative numbers.
Multiplying positive and negative numbers has far fewer rules than adding or subtracting positive and negative numbers, in fact there are only three to remember: so let’s multiply the numbers together as usual. So 4x3 = 12.
If you divide a negative number by a positive number, the odds are negative. If you divide a positive number by a negative number, the odds are also negative. If you divide two negative numbers, the relationship is positive.
If you multiply a negative by a negative, you get a positive because both negative signs are removed.
Rule 3: Subtract a negative number from a negative number: a minus sign followed by a minus sign creates a plus sign from both signs. So instead of subtracting a negative, add a positive. Basically, (4) becomes +4, so add the numbers. For example, suppose we have problem 2-4.
The characters add up physically.
Rule 2: A positive number divided by a negative number is a negative number. If you divide a negative number by a positive number, your answer is a negative number. As with multiplication, no matter what order the positive and negative numbers are, the answer is always a negative number.
The multiplication and division rule is very similar to the addition and subtraction rule.
For this, negative numbers were introduced: so that every positive number has an additive inverse. So the fact that the product of two negative numbers is positive is related to the fact that the inverse of the inverse of a positive number is the positive return number.
After you’re done multiplying and dividing, add or subtract from left to right. The order of addition and subtraction is also determined by what occurs first when reading from left to right. The sequence of operations tells you to multiply before adding.
If two positive numbers are multiplied or divided, the answer is positive. If two negative numbers are multiplied or divided, the answer is positive. If a positive number and a negative number are multiplied or divided, the answer is negative.
Rule 3: A negative number multiplied by a negative number results in a positive number. 2 x 4 are both negative, so we know the answer will be positive.
To add whole numbers with 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.
