Multiplying by 9

Start by counting by 9: 9 – 18 – 27 – 36 – 45 – 54 – 63 – 72 – 81 – 90. Are you sure you can repeat those? If so, then your multiplications are:

9 = 9 x 1

18 = 9 x 2 = 9 + 9

27 = 9 x 3 = 18 + 9

36 = 9 x 4 = 27 + 9

45 = 9 x 5 = 36 + 9

54 = 9 x 6 = 45 + 9

63 = 9 x 7 = 54 + 9

72 = 9 x 8 = 63 + 9

81 = 9 x 9 = 72 + 9

90 = 9 x 10 = 81 + 9

And your multiplication table for today is:

Science π¬

Saturn

Saturn is the sixth planet from the Sun and it has 60 moons. Like in case of Jupiter, that number has been growing. I think I need to look further into this phenomenon… What makes Saturn special though are the rings around it. They are around the equator and made up of ice, dust and rocks. But mostly ice. It’s really cold in outer space after all!

You know how we said that it took Jupiter forever to get around the Sun? Well, it takes more than double that for Saturn to complete a full circle: 29.4 years! Its day is only a little bit longer than Jupiter’s – 10.7 hours.

Saturn is 95 times the mass of Earth. It is only slightly smaller in diameter than Jupiter though. The surface is made up of hydrogen and helium and is a gas. As you go in towards the core, the gases first turn into liquid and planet’s core is actually a hard rock.

One of Saturn’s moons is the second largest moon in the Solar System. It’s called Titan and has a dense atmosphere made of nitrogen. Humans can actually breath nitrogen without getting hurt – it makes up a large portion of Earth’s atmosphere, too.

Rome – culture

Like the Greeks, Romans didnβt always have kings or emperors (who are kind of like kings). For a long time, their government was formed as a republic, with senators elected for a pre-set period of time. Does that sound familiar? A lot of countries around the world do that today. Romans also developed a law system that we make ours look like. They wrote down their laws and everybody had to follow them the same. One great idea that countries in the Western World still follow is that you assume somebody is innocent until proven guilty.

Famous writers named Virgil, Cicero, Horace and Ovid lived in Ancient Rome. A lot of books are still influenced by the way they wrote. Oh, and did I mention they spoke Latin? You may not have heard about this language yet, but you have probably heard words in Latin before. A lot of doctors still learn Latin because various medications and body parts have names in that language, so itβs easier to learn medicine if you can understand it.

Speaking of medicine: Romans were the first ones to have battlefield medics. Roman army was much more organized than those of other countries back then. Each soldier had a specific job and they were taught to fight together properly. They had soldiers whose job was to help wounded people during battle. This saved a lot of lives!

As you probably noticed, Romans were great at bringing order and structure to everything they did. Here is another thing that they decided needed to be put in order: days of the year. They have created the first calendar. It was called Julian calendar and it was a lot like ours. They were the ones that came up with the idea of a leap year! Currently, we used Georgian calendar, which is only slightly changed from Julian calendar.
