One visualization of multilication is to consider (say 7 x 35) as a grid of dots, 7 dots wide and 35 dots high. Then count up the number of dots in that rectangle. Perhaps simpler is to multiply 7 x (30 +5) = 7 x 30 + 7 x 5; = 210 + 35 = 245.
Ignoring the dots(.) as background, it can look something like: |..............................x...... |.........................x........... |...............................x..... |...........................x......... |..............x...................... |....................x................ |.............x....................... |.....x............................... |...................x................. --------------------------
A number increased by four.
One of the blades will have a series of round dots and X's. A year ending in 0 will have 5 x's and 5 dots. Each year after that will lose one dot or x. Other markings indicate the proper decade to determine the production year.
4 x 4 x 4 x 4 = 256
※ ive yet to figure it out myself
(6+5+4+3+2+1) x 4 = 84

If the X with 7 dots is supposed to represent valance electrons, then the element would be Iodine, I. There is not an element with just an X symbol. When I teach valance electors, I use an X to represent any chemical symbol and then show the order of the placement of the valance electron dots around the X.

4800 X 1200 dpi means 4800 x 1200 dots per inch which is the no. of dots a printer makes per inch to create an actual image.
