is this any easier than putting a zero on the end then adding the same number ?

[mathtutordvd]

@nzbsnowman You could definitely do that. But most people would have a harder time keeping that first number in their head and mentally adding more numbers to it, especially for larger numbers. Thanks!

Hi need some help cannot get 11's wo work out with numbers that end in zero example 11X 30 , 40 times 11 , I get a answer with a difference of 1 diget please explain htis

[mathtutordvd]

@thenitap It works the same way. No difference. 40x11...add 4+0 = 4. Sandwich this between the numbers....answer is 440. Thanks!
