Okay, so like 12 x 14 seems a little difficult to do in your head, right?

Separate 14 into 10 and 4

Now multiply 12 x 10 (120)

Multiply 12 x 4 (48)

Add together your two results (120 + 48)

And you get 168.

Much easier than trying to line it all up in your head and mental math it using the classic approach.

Counterpoint being that it's faster and easier to do on paper "normally" rather than breaking it all down.
