Multiplication is one of the four basic operations in arithmetic, along with addition, subtraction, and division. Multiplication can actually be considered repeated addition, and you can solve simple multiplication problems by adding repeatedly.
Our multiplication worksheets start with the basic multiplication facts and progress to multiplying large numbers in columns. We emphasize "mental multiplication" exercises to improve numeracy skills.
Direct link to Peter Collingridge's post “It means having multiple ...” It means having multiple or many copies of something or some group of things. For example, you might have a group of five apples and want to know how many apples you have if you had another group of five apples. This would be 5 multiplied by 2.
