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.
