Multiplication is Repeated Addition

We know multiplication is repeated addition. Let us have a quick recall of what we have learnt about
multiplication.

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

= 122

122

= 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 34

34 of a glass. How many bottles of fresh orange juice did Andrea use?

Repeated addition:

Multiplication:

¾× 8

= 244

244

= 6

Doreen used 6 bottles of fresh orange juice.

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