Facts

• Multiplication is an arithmetic operation that involves the repeated addition of the same number.
  • For example, if you have 3 bags and each bag contains 4 apples, then you have a total of 12 apples. You can express that math problem in 2 different ways using repeated addition:
    • 3 + 3 + 3 + 3 = 12 apples
    • 4 + 4 + 4 = 12 apples
• Multiplication can be thought of as a way of simplifying the operation of repeated addition.
• It is common to use the phrase "times" as a form of shorthand, substitution, replacement, or synonym for the phrase "multiplied by".
  • For example, the following sentences are equivalent:
    • Three times four is twelve.
    • Three multiplied by four is twelve.
• Multiplying zero with any number results in the product always being zero.
• Multiplying one with any number results in the product always remaining the original number.
• Multiplying a negative number with a positive number results in the product always being a negative number.
• Multiplication is part of the four basic arithmetic operations in mathematics.
• There are several arithmetic symbols for multiplication:
  • the cross ×
  • the dot ⋅
  • the asterisk *
