In the hexadecimal system, 16 units of an order equal to a higher order, so 16 digits are used: ten decimal system the letters A, B are added, C, D, E, and F. In the binary system, two units of an order equivalent to a higher order, so it is a system that uses only ones and zeros. In computing, for example, binary, octal and hexadecimal systems are used. There are other various positional decimal systems. Each rod corresponds to an order of units: When a rod 10 gather accounts are removed and replaced by a ring or ball onto the blade on your left. In its simplest form, an abacus is a device consisting of a horizontal base with various vertical rods, which "accounts" (perforated rings or pellets) are inserted. In some countries, despite the advent of electronic calculators, it is still quite common to see people doing some calculations with the abacus. The abacus is an instrument for understanding the relationship between units of different order very well and also perform simple arithmetic operations. For example, the number 72.483 can be decomposed as follows: We can also decompose a decimal number analogously as we did before. Thus arises the tenths, hundredths, thousandths, ten thousandths, etc. To represent numbers less than the unit used the same equivalence relations between units orders, but now in decreasing order. For example, the number 75,269 can be decomposed as follows: Therefore, a number is equal to the sum of the products of their numbers for their respective values. So, ten units are a dozen ten scores are one hundred ten hundreds form a thousand, etc. We say that is because ten decimal units of a particular order equivalent to a unit of higher order. The value of the second 7 is seven units, but the value of the first 7 is 700 units. We say that is because the positional value of a digit depends on its place in the number: the first number 7 757 not worth the same as the second 7. Our current numbering system is a positional decimal system. Some of them, like the Roman or sexagesimal of ancient Babylon, there are still some traces in our society, yet is written in some cases the year MMX or time 18:56, for example. Throughout history, civilizations used different numbering systems. Even numbers used to encode information as diverse as: text, images, sounds, videos. We use them to count, to express the result of a measure, to perform calculations. Can you imagine a world without numbers? Think for a moment how we would live if there were no numbers. They should now read 4, blank, and 8, making your answer 408.In our daily life we constantly use the numbers. Record the product of the last two digits 4 and 2 (8), in the last of the answer columns.Since you're adding a 4 to a 6 in that column, carry one bead over to the first answer column, making a 4 in the seventh column (four beads from the bottom section pushed up to center bar) and a 0 in the eighth (all beads in their original starting position: the top section bead pushed up, bottom section beads pushed down).
