Explain the double fact when you multiply by 2
When you multiply a number by 2, you are essentially doubling the value of that number. This is often referred to as the "double fact." For example, if you multiply 3 by 2, you get 6, which is double the value of 3.
To understand why this happens, let's look at the concept of multiplication. Multiplication is a mathematical operation that combines groups of equal values. When you multiply a number by 2, you are adding together two equal groups of that number.
To find the double of a number, you can use the following steps:
1. Start with the number you want to double.
2. Add the number to itself. This can be done by adding the number to itself or multiplying the number by 2.
3. The result is the double of the original number.
For example, let's say we want to find the double of 4 using the steps mentioned above:
1. Start with 4.
2. Add 4 to itself: 4 + 4 = 8.
3. Therefore, the double of 4 is 8.
This double fact property is an important concept in mathematics and has many practical applications in real-life situations, such as doubling quantities, calculating discounts, or determining the cost of multiple items.
