Thank you GWB.

EDIT: If you asked me that at the start of 4th grade, I would of needed paper and pencil because I was taught to stack the numbers, not exactly something you can visualize with some one barking in your face - it happened.

Using lazy math, 60 x 6 = 360 because 6x6=36 and you add a zero. Doing more lazy math 2x6=12. Doing simple addition 360 + 12 = 372. It's the scenic route but it works without paper and pencil on the fly.

62 x 6 = 372

Strange but there might be an upside to this all
