Four fives
you multiply 5 by 2 which is ten or you think of adding 5 two's or adding 2 fives.
Well, honey, one way to get four fives to equal 30 is to add them all together: 5 + 5 + 5 + 5 = 20. Then, multiply that by the remaining 5: 20 x 5 = 30. Another way is to get creative and arrange the fives like this: (5 + 5) x (5 - 5) = 10 x 0 = 0 + 30 = 30. Voilà!
4545 * 2 = 90You can do this in your mind by adding 40 + 40 = 80, then add the two fives 5 + 5 = 10, and add those two sums together. 80 + 10 = 90.
In order to find the answer to a muliplication problem you first line up the the one's column of the two digits, placing the greater number on top of the one with a lower value. Let's call the lower valued number X and the higher number valued number Y. Okay, first multiply X's one's column digit by Y's. Place the answer beneath. Then multiply X's one's column digit by Y's hundred's column (If necessary) That should give you the answer if your solving with two one-digit numbers. However if you're solving the problem with two-digit numbers the procedure is different. You must place a zero below the original answer in order to continue to multiply the remaining factors. Then if X still has another digit to multiply by Y you add another zero beneath that product. And then add all of the products from the problem. Though, if you need to know how to solve a one-digit problem you go like this: Say I needed to multiply 5*5=. Well you know you need to add 5 fives together to get the answer so, 5+5=10+5=15+5=20+5=25. That's using 5 fives! So the answer to 5*5=25. If you follow that method other problems should be very easy.

You can break a hundred dollar bill into smaller denominations by visiting a bank or a store that offers cash back services. Simply ask the cashier to exchange your hundred dollar bill for smaller bills, such as twenties, tens, or fives.
Two fives and four ones
There are 200 five dollar bills in 1000 dollars. This calculation is done by dividing the total amount by the value of each bill: 1000 / 5 = 200. Each five dollar bill contributes $5 towards the total amount, and by dividing the total by the value of each bill, we can determine how many bills are needed to make up the total.
Green and white $5 bills with the large portrait of Lincoln inside an oval have a somewhat fuzzy watermark that's similar to the portrait. Newer gray and purple fives have the number "5".
Dollars and cents. The cents are: pennies, nickels, dimes, quarters, and half dollars. Dollar bills come in ones, twos (rarely, though), fives, tens, twenties, fifties, and hundreds.
