What does the word array mean in math?
An array is a set of numbers that form some sort of regular arrangement. A linear array is a 1-dimensional array consisting of a row or a column of a set of numbers. A 2-dimensional array is a rectangular arrangement of numbers. And there are arrays with higher dimensions. The elements of an array need not be numbers: they could be variables, functions or expressions. In other words, it's a picture to describe a multiplication problem.
What multiplication fact can be found by using the arrays for 2 times 9 and 5 times 9?
Oh, what a happy little question! When you have an array for 2 times 9, you can see 2 rows of 9, which equals 18. And when you have an array for 5 times 9, you can see 5 rows of 9, which equals 45. Keep exploring those arrays and you'll create a beautiful landscape of multiplication facts!
