How to multiply in your head

What is 6 x 40?

  • 6 x 40 is equal to 6 x 4 x 10
  • 6 x 4 is equal to 6 x 2 x 2
  • 6 x 2 x 2 = 24
  • 24 x 10 = 240
  • This means 6 x 40 = 240

Break down the calculation as much as you need to. If you know 6 x 4 = 24, you don't have to break it down into 6 x 2 x 2.
