Math

The first thing we did in Maths was to find out different types of things that has big numbers.
Examples: How many sands are there on earth
Example: How many stars are there in each galaxies

And then we worked out the distances from our planet to the other planets. Then we worked out how long it would take in days, hours and years to get to the other planets

We have been learning about how long to travel from planet to planets in days/kilometres using the airbus.

We were learning things about the planets around the solar system. We first found out the distances between the planets and found out what the whole is. And then we worked out the percentage of the planets.

Here's how we calculated the distances of each planets.

Mars to Jupiter

550,400,000 km

550.4

550 x 10^6

12%

We minus the larger distance from the small distance

Example:

Sun to Planet distance

Jupiter to Saturn

648,700,000 km

648.7

648 x 10^6

14%

Mercury to Venus

Mercury = 57,900,900

Saturn to Uranus

1,444,000,000 km

1,444

1,444 x 10 ^ 6

32%

Venus = 108,200,200

Venus is the large distance than Mercury

The Mercury's distance is small so we subtracted the distance of the Mercury to Venus's distance

Uranus to Neptune

1,626,100,000 km

1,626.10

1,626 x 10 ^ 6

36%

Because the distance of the Mercury is small then we minus it to large distance which is Venus

If we add all of our percentage of he planets, it comes 100%

Whole =4,500,000,000

Whole=100%

4,500

x 10 ^6 km

Here's where we found the distances and finding out the answers.. https://www.enchantedlearning.com/subjects/astronomy/planets/

We have been learning about how to calculate large numbers in different ways.

Here are the work we've done:

Index Notation

Example of writing Index Notation is 2 x 2 x 2 x 2 x 2 = 25

The result of 25 or the meaning of it is 25 = 2 x 2 x 2 x 2 x 2 = 32

What I do to know the result of 25 , first you need to times 2 x 2 = 4 then times it again in 2 = 8

Calculating powers

You can use the xy key on a calculator or in your phone

I’ll give Example:

Calculate the value of 105

Follow this steps on your calculator:

(10)(xy)(5)(=)

So = 10x10x10x10x10=100,000

So 105=100,000

The First Index Law

You can just get the result by adding up the powers

For Example:

62 x 65 = (6 x 6) x (6 x 6 x 6 x 6 x 6 x 6)

_________________________________________________________________________________

We were working out the names of the big numbers from million to decillion and from decillion to vigintillion.
But unfortunately didn't get up to what's after decillion and to vigintillion because there was not enough time for us to get it all done. But we did find out what's after decillion.

We worked out how far is it to get to the planets using the speed of the airbus.
