Note : Any number multiplied by 0 becomes 0.
Example:
1654 × 0 = 0
Multiplication of 2 numbers a and b, written as a × b, is actually a repeated addition of the number a over b times.
Example:
6 × 4 = 6 groups of 4 = 4 + 4 + 4 + 4 + 4 + 4 = 24
To multiply numbers with more than one digit correctly, all digits must be placed in the correct position starting from the right.
Example:
Common Mistakes in multiplication
Examples A and B have numbers in the wrong positions – wrong place values.
Example C – it is hard to multiply more than 2 numbers at one time. What we do is Multiply the first 2 numbers and then use the result to multiply with the third number to get the final answer.
