Speed Math: Multiplying Decimals

Went through the chapter on Multiplying Decimals. The concept is the same as any other multiplication, but one use of it is super-cool.
If you need to multiply 8 x 88, make it 8.0 x 88. Essentially, you're multiplying 80 x 88 and can just add a decimal point at the end of your answer. Super-awesome!
To Do
Hopefully will get to go through the next chapter (Multiplying Using Two Reference Numbers) today itself.
Tables upto 20!
