3. Distributive property

In mathematics, the distributive property is a fundamental property that describes the relationship between multiplication and addition. It states that multiplying a sum by a number is equivalent to multiplying each addend in the sum by that number. This property plays a significant role in simplifying multiplication expressions and has wide-ranging applications in various mathematical operations.

• Simplifying Multiplication Expressions:
  The distributive property is commonly used to simplify multiplication expressions involving sums. For instance, consider the expression "12 x (70 + 2)." Using the distributive property, we can simplify this expression as follows:
  12 x (70 + 2) = 12 x 70 + 12 x 2 = 840 + 24 = 864
  This simplification makes it easier to evaluate the product and obtain the result of 864.
• Applications in Real-Life Scenarios:
  The distributive property finds practical applications in various real-life scenarios. For example, suppose a store sells apples at a price of $0.75 per apple. If you want to buy 12 apples, you can calculate the total cost using the distributive property:
  Total cost = 12 x $0.75 = (10 x $0.75) + (2 x $0.75) = $7.50 + $1.50 = $9.00
  In this scenario, the distributive property allows you to calculate the total cost by multiplying the price per apple with each of the 12 apples, resulting in the total cost of $9.00.

In summary, the distributive property is a fundamental mathematical property that plays a crucial role in simplifying multiplication expressions and has practical applications in various real-life scenarios. In the context of "12 x 72," the distributive property can be used to simplify the expression as 12 x (70 + 2) and then calculate the product as (12 x 70) + (12 x 2), resulting in the final product of 864.
