What are Integers?
Integers are whole numbers that can be positive, negative, or zero. They do not include fractions or decimals. For instance, -3, 0, and 7 are all integers. Multiplication of integers plays a vital role in arithmetic, algebra, and beyond.
The Basics of Multiplying Integers
When multiplying integers, there are some key rules to remember:
-
Positive × Positive = Positive: When you multiply two positive integers, the result is always positive. For example:
- (3 \times 2 = 6)
-
Negative × Negative = Positive: When you multiply two negative integers, the result is also positive. For example:
- (-4 \times -5 = 20)
-
Positive × Negative = Negative: When you multiply a positive integer by a negative integer, the result is negative. For example:
- (6 \times -3 = -18)
-
Negative × Positive = Negative: This rule is similar to the previous one. The order doesn’t change the result:
- (-7 \times 2 = -14)
Multiplication Table for Integers
Using a multiplication table can be an effective way to visualize how integer multiplication works. Below is a simple multiplication table for integers from -5 to 5:
<table> <tr> <th>×</th> <th>-5</th> <th>-4</th> <th>-3</th> <th>-2</th> <th>-1</th> <th>0</th> <th>1</th> <th>2</th> <th>3</th> <th>4</th> <th>5</th> </tr> <tr> <th>-5</th> <td>25</td> <td>20</td> <td>15</td> <td>10</td> <td>5</td> <td>0</td> <td>-5</td> <td>-10</td> <td>-15</td> <td>-20</td> <td>-25</td> </tr> <tr> <th>-4</th> <td>20</td> <td>16</td> <td>12</td> <td>8</td> <td>4</td> <td>0</td> <td>-4</td> <td>-8</td> <td>-12</td> <td>-16</td> <td>-20</td> </tr> <tr> <th>-3</th> <td>15</td> <td>12</td> <td>9</td> <td>6</td> <td>3</td> <td>0</td> <td>-3</td> <td>-6</td> <td>-9</td> <td>-12</td> <td>-15</td> </tr> <tr> <th>-2</th> <td>10</td> <td>8</td> <td>6</td> <td>4</td> <td>2</td> <td>0</td> <td>-2</td> <td>-4</td> <td>-6</td> <td>-8</td> <td>-10</td> </tr> <tr> <th>-1</th> <td>5</td> <td>4</td> <td>3</td> <td>2</td> <td>1</td> <td>0</td> <td>-1</td> <td>-2</td> <td>-3</td> <td>-4</td> <td>-5</td> </tr> <tr> <th>0</th> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> </tr> <tr> <th>1</th> <td>-5</td> <td>-4</td> <td>-3</td> <td>-2</td> <td>-1</td> <td>0</td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> </tr> <tr> <th>2</th> <td>-10</td> <td>-8</td> <td>-6</td> <td>-4</td> <td>-2</td> <td>0</td> <td>2</td> <td>4</td> <td>6</td> <td>8</td> <td>10</td> </tr> <tr> <th>3</th> <td>-15</td> <td>-12</td> <td>-9</td> <td>-6</td> <td>-3</td> <td>0</td> <td>3</td> <td>6</td> <td>9</td> <td>12</td> <td>15</td> </tr> <tr> <th>4</th> <td>-20</td> <td>-16</td> <td>-12</td> <td>-8</td> <td>-4</td> <td>0</td> <td>4</td> <td>8</td> <td>12</td> <td>16</td> <td>20</td> </tr> <tr> <th>5</th> <td>-25</td> <td>-20</td> <td>-15</td> <td>-10</td> <td>-5</td> <td>0</td> <td>5</td> <td>10</td> <td>15</td> <td>20</td> <td>25</td> </tr> </table>
