# Multiply Three or More One Digit Numbers (Within 100)

**a) **To multiply three numbers, group any two numbers and find their product. Then, multiply the obtained product by the third number.

**For example:** To find 1 x 2 x 3, group first two numbers and find their product.

(1 x 2) = 2

Now, multiply the obtained product by the third number.

2 x 3 = 6

So, 1 x 2 x 3 = 6.

**b) **To multiply four numbers, make two groups by taking any two numbers and find their products. Then, multiply the obtained products together.

**For example:** To find 1 x 2 x 3 x 4, make two groups by taking any two numbers and find their product.

(1 x 2) = 2

(3 x 4) = 12

Now, multiply the obtained products together.

2 x 12 = 24

So, 1 x 2 x 3 x 4 = 24.
