How can adding doubles can help you to multiply by 2 give an example?
Mulitplying is really just a form of addition. Multiplying by 2 is the same as adding a number to itself (or adding doubles). For example: 4X2 is the same as 4 + 4 = 8 The X2 part of the multiplication problem means that you are adding doubles or 4 to itself. So any problem with X2 would be the same as adding doubles: 5X2 = 5 + 5 = 10 6X2 = 6 + 6 = 12 7X2 = 7 + 7 = 14 ...and so on. So if you can add doubles you already know how to multiply any number by 2.
