![]() ![]() For any two integers, a and b:Īccording to the associative property, changing the grouping of two integers does not change the result of the operation. ![]() Z is closed under addition, subtraction, multiplication, and division of integers. The closure property states that the set is closed for any particular mathematical operation. The main properties of Integers are as follows: Adding and Subtracting Integers Worksheet Grade 7.Adding and Subtracting Integers Worksheet Grade 5.Therefore, (-15) ÷ 3 = -5 Integers Worksheetsĭownload integers worksheets, including addition and subtraction of integers, adding and subtracting multiple integers, and multiplication and division of integers. Solution: Using the rules of division of integers, when we divide a negative integer by a positive integer, the quotient has a negative sign. In order to carry out the division of two integers, we use the following rules. The different rules and the possible cases for the division of integers are given in the following section Rules of Integers in Division For the division of integers, we use the rules given in the following table. Hence, the result gets a negative sign, "-”.ĭivision of integers means equal grouping or dividing an integer into a specific number of groups.Now, among 7 and 10, 10 is the larger number and its original sign “-”.Their difference (larger number - smaller number) is 10 - 7 = 3.Here, the absolute values of 7 and (-10) are 7 and 10 respectively.Now, the rules for this operation will be the same as for the addition of two integers.Convert the given expression into an addition problem and change the sign of the subtrahend, so, we get: 7 + (-10).Solution: 7 - 10 can be written as (+ 7) - (+)10 Apply the same rules of addition of integers and solve the problem thus obtained in the above step.Įxample: Subtract the given integers: 7 - 10.Convert the operation into an addition problem by changing the sign of the subtrahend.In order to carry out the subtraction of two integers, we use the following rules: The different rules and the possible cases for the subtraction of integers are given in the following section. Subtracting integers is the process of finding the difference between two or more integers where the final value might increase or decrease depending on the integer being positive or negative. We move 10 units to the left side from 5.įinally, we reach at -5. The next number in the given problem is -10, which is negative. So, we start from 0 and move 5 units to the right side. In the given problem, the first number is 5 which is positive. Move to the left side, if the second number is negative.Įxample: Find the value of 5 + (-10) using a number line.Move to the right side, if the second number is positive.The rules for the addition of integers on the number line are as follows. ![]() We can also solve the above problem using a number line. Hence, the result will be a positive value. Now, among 2 and 5, 5 is the larger number and its original sign “+”. ![]() Their difference (larger number - smaller number) is 5 - 2 = 3. Here, the absolute values of (-2) and 5 are 2 and 5 respectively. Hence, the result gets a negative sign, "-”.Įxample: Add the given integers: (-2) + 5 Now, among 2 and 5, 5 is the larger number and its original sign “-”. Their difference (larger number - smaller number) is 5 - 2 = 3 Here, the absolute values of 2 and (-5) are 2 and 5 respectively.
