Together, we'll see that multiplication is all about adding equal groups together. We'll find that 5 groups of 3 acorns each can be represented as 5 times 3, which equals 15 acorns. video https://cdn.kastatic.org/googleusercontent/G1N-BovBj7ntbTlX204l6LagHq6ESyjLtmm9HId_3wnBrx4JDqd4zFi1DKrC39VBoLNNdOOEbBxfRS7FPKU5msD7 Introduction to multiplication Let's dive into the concept of multiplication using the example of a squirrel collecting acorns.
