the same as adding whole numbers. two negatives = negative. two positives = positive, and a negative and positive depends on the absolute value of the greater number.
The rule for subtracting negative numbers is 'when you are subtracting a negative number from a positive or negative, you must always add it.'Example: 3--3 = 3+3 = 6
if the signs are the same you must add its opposite.
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
-15. The rule is 'subtracting a positive is the same as adding a negative'
divide them or multiply then put a negative because to different signs make a negative to of the same signs make a positive
Like signs give a positive answer. Unlike signs give a negative answer.
The result in such cases is always negative.
if both have the same sign the answer is positive, if they have different signs the answer is negative.
The answer is 22. The rule is "adding a negative is the same as subtracting a positive." - In this case, 41-19=22
Multiply two integers disregarding the signs. Then if the signs are the same, the answer is positive and if the signs are different, the answer is negative. Alternatively, if you are multiplying together a whole bunch of numbers, first find the product while ignoring the signs. Then count all the negative numbers. If the count is even, the answer is positive and if it is odd, the answer is negative.
The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.
Positive x negative = negative (Negative x positive = negative) Positive x positive = positive Negative x negative = positive So if the signs are the same the answer is positive and if they are different it is negative.
Subtracting a positive number from a negative number is the same as adding two negative numbers, which is like adding two positive numbers except you're going to the left from zero on the number line instead of to the right. The rule is to add the absolute values (the numbers without the signs) of the two numbers and keep the negative sign. For example, -3 - 5 = (-3) + (-5) = -1 * (3 + 5) = -8.
Never subtract an /a 0 .
The product is positive.The rule is, "Numbers with like signs give a positive product.", and conversely, "Numbers with unlike signsgive a negative product."
If the two numbers have different signs, then the result will be negative. If the two numbers have the same signs, the result will be positive. This assumes all the numbers are non-zero.
always a positiveMultiplying and dividing rule:(remember this; it's very useful) When you multiply or divide two numbers . . .-- If they both have the same sign, then the answer is positive.-- If they have different signs, then the answer is negative.
Adding/SubtractingWhen adding and subtracting two numbers with different signs, you always follow this rule:If the negative is before the positive number, then switch them-5+4 to 4-54-5 is -1.You could also switch the signs from -5+4 to 5-4you end up with one, but the answer will have the same sign as the larger number.So you still end up with -1.If the positive number is before the negative, Ex:6+-2and the larger number is the positive number, you follow the "Keep it. Change it. Change it." Rule.Keep the 6.Change the + to -Change the -2 to a +2, also written as 2So, 6-2.answer would be 4.
rule where the answer will always be positive BECAUSE: Product means you're doing multiplication. positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative
While solving problems with large integers, don't always rely on the number line. Using integer arithmetic we can solve the problem of large integer. We need a rule for subtracting integers and the rule is: Rule: To subtract an integer, add its opposite.
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
