multiplication
A math operation for quickly adding equal groups together.
Multiplication is a mathematical operation that combines equal groups to find a total. When you multiply 4 times 3, you're really asking “what do I get if I have four groups of three?” The answer is 12, because 3 + 3 + 3 + 3 equals 12.
Think of multiplication as a shortcut for repeated addition. If you're setting up chairs for a school assembly and you need to arrange 8 rows with 12 chairs in each row, you could add 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12, but it's much faster to multiply: 8 × 12 = 96 chairs.
The numbers being multiplied are called factors, and the result is called the product. In the example 6 × 7 = 42, the factors are 6 and 7, and the product is 42.
Multiplication shows up everywhere: calculating the area of a rectangle, figuring out how much money you'll have after saving the same amount each week for several weeks, or determining how many legs are in a room full of chairs (4 legs per chair times however many chairs you have). Learning your multiplication tables, those grids of products from 1 × 1 up through 12 × 12, gives you a powerful tool for solving problems quickly.
