Actually, I do math like that (2 digit times a 1 digit) a little different. I multiply the first number in the two digit times the 1 digit number (i.e. 20 x 7 = 140) then I multiply the second number by the single number (4 x 7 = 28) and then I add them together (140 + 28 = 168). So I basically do it the opposite way I was taught. I don't know why I do it that way, I just do.
