This Online Integer Operations Practice is a great way to put your skills to the test in a fun environment. By practicing, you’ll start to recognize the answers instantly, without needing to count every time.
Integer Operations Practice
The best way to get good at integer operations is to do it often. This Integer Operations Practice is an interactive and engaging web-based application designed to help users practice and improve their integer skills through mental math.
There are rules for integer operations. When adding numbers with different signs, subtract the smaller number from the larger one and take the sign of the larger number. When you subtract a negative number, it’s the same as adding a positive one. When multiplying or dividing two numbers with the same sign, the answer is always positive. If they have different signs, the answer is always negative. Scroll down the page if you need a more detailed explanation.
This Integer Operations Practice allows you to select one or more operations: addition, subtraction, multiplication division. It has an option for a 60-second timer, encouraging players to solve the problems quickly and efficiently.
Select the operations you want to practice.

Strategies for Integer Operations
Learning to perform integer operations in your head is a powerful skill that can make math much faster and more intuitive. Instead of counting, you’ll learn to see the relationships between numbers to quickly find the answer.
Integer Rules
Addition
The rule for adding integers depends on whether the numbers have the same sign or different signs.
Same Signs: If both numbers are positive or both are negative, you add their absolute values and keep the common sign.
Example 1: 5+3=8
Example 2: (−5)+(−3)=−8
Different Signs: If the numbers have different signs, you subtract the smaller absolute value from the larger one. The answer will have the sign of the number with the greater absolute value.
Example 1: (−5)+3. The absolute values are 5 and 3. Subtracting them gives you 2. Since 5 has the larger absolute value and it is negative, the answer is −2.
Example 2: 5+(−3). The absolute values are 5 and 3. Subtracting them gives you 2. Since 5 has the larger absolute value and it is positive, the answer is 2.
Subtraction
The easiest way to subtract integers is to change the problem into an addition problem. You keep the first number, change the subtraction sign to an addition sign, and flip the sign of the second number. Then, you follow the rules for addition.
Example 1: 5−(−3). Keep the 5, change the subtraction to addition, and flip the sign of -3 to positive 3. The problem becomes 5+3=8.
Example 2: (−5)−3. Keep the -5, change the subtraction to addition, and flip the sign of 3 to negative 3. The problem becomes (−5)+(−3)=−8.
Example 3: 5−3. Keep the 5, change the subtraction to addition, and flip the sign of 3 to negative 3. The problem becomes 5+(−3)=2.
Multiplication & Division
The rules for multiplication and division are the same. You just perform the operation as you normally would, and then determine the sign of the answer based on the following rules.
Same Signs: If the two integers have the same sign (both positive or both negative), the answer is always positive.
Example 1: 5×3=15
Example 2: (−5)×(−3)=15
Example 3: 12÷3=4
Example 4: (−12)÷(−3)=4
Different Signs: If the two integers have different signs (one positive and one negative), the answer is always negative.
Example 1: 5×(−3)=−15
Example 2: (−5)×3=−15
Example 3: 12÷(−3)=−4
Example 4: (−12)÷3=−4
