Of all the mental math tricks in themathlab.com POWERZONE, we feel this trick is the most powerful, because we use it the most. In fact, this trick can be used in place of many of the other tricks. If you only want to learn one trick, this is the one to learn. So here goes. The basis of this trick is the process of ripping apart a number into its simpler parts and then using those simple parts instead of the whole number all together. For example:
Multiplying by 37 mentally is a bit difficult, so we rip it apart into
30 + 7. Now it's easy to multiply by 30 and also by 7. Then we simply
add the two products together. EX: 37 x 5 =
(30+7)5 EX: 49 x 7 =
(50-1)7 EX:
127 x 6 = (100+20+7)6 EX:
3.8 x 5 = (3+0.8)5 or if you prefer another approach Think:
3.8 x 5 = (4-0.2)5
