Number Lines and One Liners

The biggest math problem that Batman learns is that 1 is the loneliest number in the world, and family is everything!

“Black. All important movies start with a black screen. And music. Edgy, scary music that would make a parent or studio executive nervous. And logos, really long and dramatic logos…”

Everything about the Lego Batman movie screams black and mathematics, from his impossible abs of 9, to the total amount of super villains he faces (we only counted up to 39, and that’s not even including Sauron and the oddity that is Condiment man!), to the amount of time it takes to heat up a plate of lobster thermidor…

In this movie, Batman leaps through many obstacles to conquer his biggest fear: being part of a family. The death of his parents left him afraid of letting anyone close, for fear of losing them. Still, he finds his team of 1 multiplying into a full blown family of 4. And though Batman keeps his adoration for all things black and brooding, his home is no longer an empty nest of darkness.

Number lines provide a more visual understanding of various forms of mathematics, including multiplication. By using a number line, the above illustrates how Batman skips 5 times to the value of 2 to get to the answer. Therefore, the answer is 10.

The following shows the same method in use, but this time, try figuring out the entire problem and equation just by looking at the skipping in the number lines:

  1. The first line shows that Batman skips 4 times to the value of 3, thus resulting in 12. This provides us with the answer: 4 x 3 = 12
  2. The second line shows that Batman skips 7 times to the value of 3, thus resulting in 21. This provides us with the answer: 7 x 3 = 21

So if you’ve ever had a fear of multiplication, be like Batman and skip it all away!
