# Multiplication is Repeated Addition

We know multiplication is repeated addition.

Consider the following:

(i) Andrea made sandwiches for 12 people. When they shared it equally, each of them got ½ a sandwich. How many sandwiches did Andrea make?

Repeated Addition:

We know each people will get ½ a sandwich.

Multiplication:

½ × 12

= $$\frac{12}{2}$$

= 6

Therefore, Andrea made 6 sandwiches and shared with 12 people each of them got ½ a sandwich.

(ii) Doreen then poured out a few bottles of fresh orange juice equally among the 8 people. Each of them got $$\frac{3}{4}$$ of a glass. How many bottles of fresh orange juice did Andrea use?

Repeated addition:

Multiplication:

¾× 8

= $$\frac{24}{4}$$

= 6

Doreen used 6 bottles of fresh orange juice.

So, would you like to still continue adding or would you rather multiply.

Since from the above examples, we can understand clearly that multiplication is faster.
