This astonishing method for multiplying numbers is<br />
so easy because it works from left to right<br />
Suppose you want to know the cost of 6 hinges at<br />
73c each.<br />
� 73 x 6 = 438<br />

IN THE DIY SHOP<br />
We first multiply the 7 by 6 to get 42.<br />
We then multiply the 3 by 6 to get 18.<br />
42 18 = 438<br />
The 1 in the 18 is mentally carried back to the 42<br />
to make it 43.<br />
So any double figure number after the first involves<br />
carrying the first figure to the left and adding it on.<br />
