Multiply by Greater Numbers

The symbol x and * are both used to indicate multiplication

To multiply greater numbers by 1 digit number, first multiply the ones, then the tens, and then the hundreds by the one digit number

If the product is greater than 9, we need to regroup

14 ones is equal to 1 tens and 4 ones. 14 tens is equal to 1 hundreds and 4 tens. 14 hundreds is equal to 1 thousands and 4 hundreds

The symbol x and * are both used to indicate multiplication

To multiply greater numbers by 2 digit number, first multiply by the ones, then by the tens

Add the products of ones and tens to get the final product

In the partial products method, we need to keep track of the place value of each digit

To multiply a 2 digit number by 1 digit number using partial products, divide the number into two parts and multiply both the parts separately by the 1 digit number

To multiply a 2 digit number by another 2 digit number using partial products method, divide both the numbers into two parts and then multiply all the parts

Add all the partial products to get the final product
