Repeated addition is a fundamental mathematical concept that serves as an introduction to multiplication. It involves adding the same number multiple times to find a total, which is equivalent to multiplying that number by the count of additions. For example, adding 3 five times (3 + 3 + 3 + 3 + 3) yields 15, which is the same result as multiplying 3 by 5 (3 × 5 = 15). This method helps visualize multiplication as a series of equal increments, reinforcing the relationship between addition and multiplication.

Repeated addition is commonly taught in early elementary education to build foundational arithmetic skills. It bridges the gap between basic counting and more advanced operations, allowing students to understand multiplication as an efficient alternative to repeated addition. For instance, calculating the total number of objects in multiple groups of equal size (such as 4 apples in each of 6 baskets) can be approached by adding 4 six times or by multiplying 4 by 6.

While repeated addition is a useful pedagogical tool, it is not typically used for complex calculations in advanced mathematics. Instead, it serves as a conceptual framework to develop fluency in multiplication tables and to foster number sense. Understanding this principle also aids in grasping related concepts like division, fractions, and algebraic expressions, where repeated addition can represent scaling or grouping.

In summary, repeated addition is a simple yet powerful method for introducing multiplication, helping learners transition from basic arithmetic to more sophisticated mathematical reasoning.
