(2) Simplify the following mathematical expression: –304 − (–17) + (−20) = ?īe careful with negative signs when answering questions like this one. STEP 2: Do the subtraction in order to solve the problem. STEP 1: Deal with adding the positive numbers. Tip: For simplicity, you might want to do the addition before performing the subtraction. (1) Simplify the following mathematical expression: 205 + 56 – 38 = ? If you have to take an advanced math examination, you will also need to understand integer rules for positive and negative integers in order to solve algebra and college-level math problems. You will need to solve basic equations that contain positive and negative integers on most exams. Integers are positive and negative whole numbers.Īccordingly, integers do not contain fractions or decimals. Therefore, -12/-4 = 3.You will need to know integer rules for both positive and negative integers for your math test. Both the 12 and the 4 are negative, so we know our answer is going to be positive. So, for example, we may have the problem -12/-4. Rule 3: A negative number divided by a negative number gives you a positive number.Įxample 3: This is also new-and doesn’t seem to make much sense, but it is a rule we have to follow when dividing negative numbers. The combination of one positive and one negative number, no matter which order they come in, means your answer is going to be negative. For example, you may see it written -12/3 = -4, but don’t get confused. Please note that this also works when the negative number comes first and the positive number is second. Thus, we divide the numbers as we normally would, and then put a negative sign in front of our answer. The 12 is positive, but the 3 is negative, so our answer has to be negative. Rule 2: A positive number divided by a negative number gives you a negative numberĮxample 2: This is new – for example, you might have 12/-3. We know that 12 and 3 are both positive because there are no negative signs in front of them.
12 is positive, 3 is positive, thus, 4 is positive. Rule 1: A positive number divided by a positive number gives you a positive number.Įxample 1: This is the kind of division you’ve been doing for years, positive numbers divided by positive numbers.
We’ll repost them here for you, using division examples instead of multiplication: In other words, if the signs are the same the quotient will be positive, if they are different, the quotient will be negative.ĭividing positive and negative numbers follows the same rules as multiplying positive and negative numbers. If only one of the dividend or divisor is negative, the quotient will be negative. If both the dividend and divisor are negative, the quotient will be positive. If both the dividend and divisor are positive, the quotient will be positive. RULE 3: The quotient of two negative integers is positive.RULE 2: The quotient of two positive integers is positive.RULE 1: The quotient of a positive integer and a negative integer is negative.Division of Integers: Negative and Positive Formsĭivision of Integers is similar to division of whole numbers (both positive) except the sign of the quotient needs to be determined.
