If you want to work it in your head, try this: 21 = 20 + 1, and if we multiply we get this: 21 x 5 = (20 + 1) 5 = (20 x 5) + (1 x 5) = (100) + (5) = 105 That's the distrubutive property of multiplicatin in action. We broke the 21 down into 20 + 1, and then when we multiply that by 5, we have to multiply each "component" of the number (that is, both the 20 and the 1) by 5 to get the answer. The 5 is "distributed" over the components that make up the 21, which are (in this case) the 20 and the 1. Each one is multiplied by 5 and then the two numbers are added up to get an answer.
