The Basics of Multiplication

• Multiplication is a quick way of adding a series of numbers.

• 2 x 4 simply means to add 2 together 4 times or 2+2+2+2

• 7 x 2 simply means to add 7 together 2 times or 7+7

• The two numbers that are being multiplied are called the factors.

• When you multiply the factors together the answer you get is called the product.

The Rules of 0's and 1's

• Anything multiplied by zero will result in a product of zero– NO MATTER HOW BIG THE NUMBER IT WILL ALWAYS

BE ZERO!– ex. 9 x 0= 0– ex. 763 x 0= 0

• Anything multiplied by one will result in a product of that number– ex. 23 x 1= 23– ex. 67,826 x 1= 67,826

Tools to Help

• Draw a Picture– Multiplication problems can be solved by drawing a picture. – Ex. 3 x 4= ? – The picture shows three rows by four columns. Simply count

the number of dots total and that will be the product.• Multiplication Table

– This is a device used to find the product of two factors.– To use a multiplication table simply put one finger on one

factor (on the top) and another finger on the other factor (on the left side). Then drag your two fingers to meet.
