Arrays

Arrays

Arrays are used in multiplication which is repeated addition. Arrays are dots so like for example three times three it´s like three across and three down so it makes a square. So yesterday on the twenty second of march two thousand seventeen my teacher put us into seven groups and she gave us a sheet of big paper and wrote a number and we should make as many arrays as possible. The array should be even like the picture in this blog up here ^. So our number was twenty four and we came up as many ways to make twenty four the factors of twenty four are one, two, three, four, six, eight, twelve and twenty four. Arrays can be useful in multiplication but it will take a long time if it´s thirty three thousand and two times fifty two thousand and seven. There will be a lot of dots you can´t count all of them it will take forever. This is just one way when your solving a multiplication problem.
