420
product = times! (x)So 78 x 6 = ?78x 6------------------(6x8)= 048(6x70)=420(don't forget to write the 0 first to indicate it's 7x10 (70)not just 7!)--------------------= 468---------------------OR.....do it in your head!!think of it just as 6 x 70(the 70 out of the 78...rounding down to nearest ten makes an easy times sum!)..... (6x7 = 42 ! ...SO ... 6x70=420!)PLUS 6 x 8 ...= 48so......... 420 plus 48... = 468 !!!!!EASY!!OR JUST USE A CALCULATOR?
