2 - Multiplication


Multiplication

Doing a multiplication is adding a number several times. For instance :

2 3 = 6
4 4 = 16
3 5 = 15

When you calculate 2 times 3 you calculate 3 + 3 (you add 3 twice), when you calculate 4 times 4 you calculate 4 + 4 + 4 + 4 (you add 4 four times), when you calculate 3 times 5, you calculate 5 + 5 + 5 (you add 5 three times).

Train yourself, without looking below!

Multiplication tables

To go faster when calculating multiplications, you have to learn multiplication tables, that is to say learning by heart all the results of the multiplications with 1 number. It is a big thing to do! Fortunately, in this first Grade, you have to learn only the 2 times, 3 times, 4 times, and 5 times tables. Here are all the results you have to learn. Good luck!
